The 8(b) inventory accumulation was the next major activity. For a decentralized company like Monsanto or, for that matter, most major chemical companies, the experience of centralized information gathering was a new experience. However, we believe that the experience not only was novel, but proved to be beneficial from several points of view. First of all, it enabled us to evolve a network of expertise. Second it gave us a central data-base on which to build other information important from a corporate point of view, and permit a one-time expense for developing a system. Third, it revealed that we needed to improve our data files in some areas. And, fourth, it gave our central staff departments some surprises as to substance locations. We used the Chemical Abstract Service Registry Profile capabilities to gather all the known synonyms and added our internal numeric and common identifiers to access the file via dozens of possible names or numbers. 

The corporate file is currently run on an IBM mainframe and data are stored in Chemical Abstracts Service Registry-II format. An in-house developed graphical interface program allows searching in a very friendly manner. The technology of this software package will be replaced in the near future. This file currently contains approximately 500,000 compounds.

The world wide facilities for retrieving chemical information provided by the Chemical Abstract Service (CAS on-line) have made it a relatively easy matter to obtain CAS registry numbers of substances, and most of the numbers in this monograph were obtained via CAS on-line. We should point out that two other available useful files are CSCHEM and CSCORP which provide, respectively, information on chemicals (and chemical products) and addresses and telephone numbers of the main branch offices of chemical suppliers.

Figure 16.1 illustrates the process we recommend for obtaining chemical property data [5]. Assessors usually start with a chemical name or synonym, Chemical Abstracts Service (CAS) Registry Number, and/or the chemical structure. The first task is to confirm the identification and structure of the chemical of interest. The largest (over 30 million chemicals) and most authoritative, but a relatively expensive source of chemical identification information is the Chemical Registry file of the American Chemical Society. However, there are several...
