1. Beilstein CrossFireplusReactions Chemical Name Search using Beilstein Commander.
Use the Fact editor in Beilstein CrossFireplusReactions. If you do not know the field labels to use in the following searches, try the "list values" icon while your cursor is in the field values box.
Find the compound(s) with chemical name Mycarose.
 Look at the record for the third substance in your answer set. Change the View to Identification and get a printout that has the structure and the Field Availability table. Write your name on it, and hand in. (You should have the open form of the sugar.)
 Write down a strategy for a search on the Beilstein database to determine how many of the records for compounds in the database have the structure keyword "stereo compound" (check the IDE portion in "list values" to find the appropriate code) and chemical name Mycarose.
 Run your strategy, look at the first answer you found, and list the number of compounds found.
2. Use the MEDLINE database on PubMed (http://www.ncbi.nlm.nih.gov/PubMed/) to find a 1985 article published by W.R. Roush and S.M. Hagadorn on the synthesis of mycarose.
 Obtain a printout that includes the abstract of the article and hand it in with your name on it.
3. Use the ChemIDplus database at http://chem.sis.nlm.nih.gov/chemidplus/ to find Mycarose.
 What is the Molecular Formula of Mycarose?
 What is the Registry Number for mycarose?
Use the Registry Number for Mycarose as a search key in the Medline PubMed (http://www.ncbi.nlm.nih.gov/PubMed/) database to retrieve articles dealing with Mycarose.
 Print out the list of articles retrieved to be handed in. (You should have fewer than 10.)
 What is the main purpose of the ChemIDplus online chemical dictionary database? How does it compare in size to the number of compounds found in the Chemical Abstracts Registry File? (List the approximate numbers of compounds in each.)
4. Connect to SciFinder Scholar and search the Registry Number for Mycarose. Obtain a printout of the record for the substance to be handed in.
Notice the additional information on the substance that is given in the Chemical Abstracts database as compared to the NLM ChemIDplus database.
 Aside from the different file locator information, do you see any significant information in the SciFinder Scholar Mycarose record that is not in the full Mycarose record on ChemIDplus?
Use the Registry Number for Mycarose that you found in ChemIDplus to search the SciFinder Scholar database for journal articles on the preparation of mycarose.
 Obtain a printout for any one of the articles that includes the abstract and indexing.Notice that there is a P appended to the Registry Number and that there is a Role assigned to the indexing of the RN.
 Is the Roush and Hagadorn article among those you found?
 If not, explain why you did not find it with a Registry Number search.
5. Formula Searching.
Use the molecular formula search option in SciFinder Scholar to find all dibromobenzenes in the Registry File.
 How many substances did you find?
 What is the CAS Registry Number for the compound that has the most references associated with it?
Use SciFinder Scholar to search the molecular formula for Mycarose. [Note that on SciFinder Scholar, you do not always have to put the formula in the Hill System order, but in most formula indexes, you do.]
 How many substances did you find?
6. Another Citation Search in the SCI database.
Use the Science Citation Index to see if anyone has cited Roush and Hagadorn's 1985 article on mycarose synthesis.
 How many times was the article cited?
 Print the reference to the most recent paper that cited it in the bibliographic format and include only authors, title, and source, and hand it in. [Hint: Mark your answer, submit it, and use the Marked List to choose the format in which to print.] In the 1982-86 Chemical Substance Index to the printed Chemical Abstracts, what name is used to index Mycarose? Include the full name and the Registry Number.
