Optimizing Name MatchTo get the best results out of Name Match processing, it is important to take into account the nature of the names in CAS REGISTRYSM, and the programs that perform the matching of the names.Each substance in CAS REGISTRY is associated with a CA Index Name. These names are prepared by CAS experts using very specific rules to assure the assignment of one unique name for each substance. This is usually a highly systematic, chemically descriptive name.In addition to the CA Index Name, many substances also have other names (synonyms) associated with them. Some of these are systematic and chemically descriptive. Others are less descriptive or trivial or trade names.Specific examples of the types of names available for name match are listed in the four categories below.
