As part of the development of a computer-based chemical information system at CAS, it has been necessary to devise techniques for the registration of drawings of chemical structures. A major purpose of the CAS regis-tration process is to determine whether a particular structure has already been storedin the system. The ability to make this determination makes it possibleto utilize a computer to assign to every chemical structure a unique identifying label. Thisidentifying label, referred to as a registry number, is the thread that ties together all information associated with a particular compound throughout the developing CAS computer system. It is because of this association, made possible by the regis-tration process, that CAS will be able to provide multiple-file correlative searches with assurance that all information on file for a particular compound has been located.
