Chemical Abstracts Service online databases

More than 10 000 databases exist that provide a small or large amount of data on various topics (including chemistry). The contents in databases are supplied by approximately 3500 database developers (e.g., the Chemical Abstracts Service, MDL Information Systems, etc.). Since there is a variety of topics from economics to science, as well as a variety of structures of the database, only some of the vendors (-2000) offer one or more databases as either local or as online databases (Figure 5-4) [4]. Usually, databases are provided by hosts that permit direct access to more than one database. The search occurs primarily through different individual soft-... [Pg.230]

There has been a rapid proliferation of commercial search interfaces, such as DataStar and STN International. STN may deserve special mention since it is a science information service operated by Chemical Abstracts Service (CAS) in North America, Fachinformationszentrum-Karlsruhe (FIZ-K) in Europe, and Japan Association for International Chemical Information (JAICI) in Japan. It is available as online subscriber access to 220 databases (STN Express) and as web access (STN on the Web for experienced searchers and STN Easy for infrequent searchers). See www.cas.org/stn. html and/or www.stn-international.de/. Since Internet search techniques depend on the interface available, no detailed explanations are given here. There are several published guides to database searches for chemical and physical properties, but the situation is evolving rapidly and it is recommended that you consult a reference librarian for information about the current situation concerning search interfaces at the library you use. [Pg.703]

STN is an online database service jointly owned by CAS and FIZ Karlsruhe. Chemical Abstracts Service provides a range of online databases covering chemistry and related sciences (see also Table 1.2) ... [Pg.9]

Bob Dana and colleagues at Chemical Abstracts Service presented a poster on the machine generation of multi-step reactions for the CASREACT system on STN International. The online version of FIZ s Cheminform database will be available on STN International also. Alex Parlow gave a poster presentation on the creation of Cheminform both as an electronic database (for onhne and in-house use) and as a printed product. [Pg.479]

Chemical Abstracts Service (CAS) Registry Number This is a imique identifier assigned by the American Chemical Society to chemicals recorded in the CAS Registry System. This nrrmber is used to access various chemical databases such as the Hazardous Substances Data Bank (HSDB), CAS Online, Cherrrical Substances Irrfomration Network and many others. This entry is also useful to conclusively identify a substance regardless of the assigned name. [Pg.9]

Chemical Abstracts Service maintains a computerized database that permits users to search through Chemical Abstracts rapidly and thoroughly. This service, which is called CA Online, is described in Section 29.11. Beilstein is also available for online searching by computer. [Pg.977]

Chemical Abstracts Service is the publisher of Chemical Abstracts and corresponding products and services, which are available in the following formats printed, microform, online databases, CD-ROM, World Wide Web. Polymers selected for inclusion in the CAS Chemical Registry System and the CA Chemical Substance Indexes are indexed in two ways ... [Pg.5059]

CAS Online. This database service is available through STN, the online system operated by Chemical Abstracts Service (CAS) that provides access to several related files with a choice of interfaces. Because there is a charge for using CAS Online, it is advisable to obtain training and assistance from a search specialist before beginning searching. That assistance will improve the quality and the cost-effectiveness of the search. [Pg.910]
