Chemical Abstracts Reactions database contains information on reactions of organic substances, including organometallics and biomolecules. CASREACT contains singlestep and multistep reaction information for reactants, products, reagents, solvents, and catalysts. The sources are journals covered for CA from 1985 to the pres­ent, including the reaction collection jointly built by the All-Union Institute of Scientific and Technical Information of the Academy of Sciences of the USSR (VINITI) and the German Zentrale Informationsverarbeitung Chemie, Berlin (ZIC) and supplied by the German software company, InfoChem from 1974 to 1991, and reactions from INPI data since 1840. Structure-based reaction queries, functional groups, CAS Registry Numbers, textual reaction information, yields, bibliographic information, substance and subject indexing, and abstracts are searchable.
