When the Question is Chemical, The Answer is CAS ONLINE.
SEARCH DRUG1RESISTANCE AND 1695-77 We've just made CAS ONLINE a truly comprehensive chemical information system, offering both substance-oriented and subject-oriented searching in one efficient system. Virtually all of the access points you've "looked up" in CA indexes are now searchable on CAS ONLINE, along with other search options undreamed of in printed indexes.

Identify substances through CAS ONLINE's distinctive structure search capability. At ordinary keyboard terminals, enter a molecular structure or substructure diagram. You may define your search strategy using logical operators (AND, OR, NOT) to include or exclude specific moieties of interest. Then run your query against the Registry File of 6,000,000 substance records. You can also search the Registry File by chemical name. Our Name Match feature accesses 9,000,000 substance names. And you can save time by entering the common or trade names you're familiar with. Accessing by structure diagram or chemical name, you can retrieve a complete substance record: CAS Registry Number, molecular formula, CA index name, synonyms, and structure diagram. But aon't stop there! You can find relevant literature by automatically transferring the Registry Numbers to our CA File.
CAS ONLINE now includes a CA File for searching the CA keywords, bibliographic information, and controlled-vocabulary subject index entries. Use it to find documents on specific substances by searching the Registry Numbers you retrieved in your Registry File search. Or combine Registry Numbers with chemical terms and bibliographic identifiers of all kinds. Search strategies for the CA File can comprise CA index entries for concepts, applications, uses, properties, reactions, apparatus, processes, biological genus and species, and classes of substances, as well as Registry Numbers. Or search by author names, journal titles, patent assignees, CA section numbers and other bibliographic data. All CA Collective Index periods back through 1967 are searchable in one file. No system is more convenient for zeroing in on chemical literature—journal articles from 14,000 periodicals, patents of 26 nations and two international bodies, the entire spectrum of chemistry-related documents from 150 nations.
Retrieve CA Abstracts and Index Entries When a brief bibliographic citation isn't enough, ask for more information on CAS ONLINE. For most documents identified in your searches, you may choose to retrieve CA abstracts and/or CA index entries. These are your most concise and informative guides to the content of chemical literature.
So if you already have CAS ONLINE, you've got more reasons than ever to use it. If you don't have CAS ONLINE, please call us today about opening an account.
