作为中科院开发计算机化学信息系统的一部分，有必要设计化学结构图登记技术。CAS注册过程的一个主要目的是确定系统中是否已经存储了特定的结构。进行这种测定的能力使得利用计算机为每个化学结构分配一个唯一的识别标记成为可能。硫代识别标签，称为注册号，是将整个开发中的CAS计算机系统中与特定化合物相关的所有信息联系在一起的线索。正是由于这种关联，通过配准过程，CAS将能够提供多文件相关搜索，并确保特定化合物的所有文件信息都已被定位。
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.
