Compound registration service/system

These sources included, among others, the U. S. Pharmacopoeia and the Merck Index. Thus, the common data base would contain compounds known to be of interest to people in the health field, including drugs, antibiotics, hazardous materials, pesticides, nutrients, and food additives as well as inert compounds in such substances. Chemical Abstracts Service processed these sources against its registry system and added registrations as well as synonyms as they were found in these standard references. The data were delivered to FDA and NLM in a form suitable for processing in their machine systems.
