Registry computer search

Both common and systematic names of compounds are used throughout this volume, depending on which the Editor-in-Chief felt was more appropriate The Chemical Abstracts indexing name for each title compound, if it differs from the title name, is given as a subtitle Systematic Chemical Abstracts nomenclature, used in both the 9th and 10th Collective Indexes for the title compound and a selection of other compounds mentioned in the procedure, is provided in an appendix at the end of each preparation. Registry numbers, which are useful in computer searching and identification, are also provided in these appendixes. Whenever two names are concurrently in use and one name is the correct Chemical Abstracts name, that name is adopted. For example, both diethyl ether and ethyl ether are normally used. Since ethyl ether is the established Chemical Abstracts name for the 8lh Collective Index, it has been used in this volume The 9th Collective Index name is 1,1 -oxybisethane, which the Editors consider too cumbersome.

Initial work on the incorporation of biological Information into the compound registry and search system will deal mainly with data that is already being captured on a routine basis for computer input and storage. This Includes screening results in which the biological response of compounds to a variety of test screens is indicated by numerical activity values or binary activity assignments (actlve/lnactive). Additional data types to be Incor-...

This is the Chemical Abstracts Service (CAS) Registry number. Chemical Abstracts, published by the American Chemical Society, is a listing of the abstract or summary written for any paper in the chemical literature. Every compound made gets a number. This makes for easy searching by computer, as well as by hand. 

In 2009, there were two ways to access from a client version installed on a computer or via web access. The client version is being phased out as the web version is being developed. Both versions have the same functionality. Advantages of SciFinder include the ability to combine answer sets and the ability to see all the substances linked to an abstract in a grid layout. Clicking on a substance structure or registry number allows the user to modify the structure for future searches or to explore reactions. SciFinder also provides access to the full text of the article through the ChemPort Connection. This allows the user to directly access the article when permissions for access are enabled or to purchase the article when they are not enabled.
