化学文摘服务机构(CAS)的使命是报道世界上主要的化学和化学工程文献，长期以来一直致力于处理有关化学物质的信息。一个特别的问题是确定物质在科学文献中的重复出现。这样的标识对于保证《化学文摘》索引的一致性是必要的。这些索引以系统的化学命名法为基础，多年来一直使用的确保一致性的技术是在每次被引用时为每种索引物质命名，并按字母顺序将名称与其引用一起提交到索引中。这导致了重复重命名时的大量重复工作。为了纠正这种情况，中科院的化学品登记系统是在20世纪60年代初开发的。S的主要目标是建立一个以计算机为基础的系统，根据分子结构唯一地识别化学物质。还认识到，中科院注册号将提供一个机器地址，使包含结构信息、非文献信息、索引和书目信息的文件得以链接。此外，这一链接功能被视为一种潜在的基于物质鉴定的通用链接，最终可能涉及外部文件和数据库、主要文献和其他二级服务。最初的和实验性的计算机系统，称为登记处一，确立了充分定义的有机化学物质登记概念的可行性和有效性。第一次登记处于1964年底开始运作。1968年，随着处理更多类别的物质，该系统的范围扩大了，这一系统称为登记册二，开始纳入CAS索引业务。书记官处系统的最新版本--书记官处第三版于1974年投入使用，对书记官处的记录进行了重大调整，以使该系统更有效地支持CAS索引命名功能和计算机结构，并通过明确识别具体的环系统来实现产出操作。随着使用范围的扩大，登记处作为一种物质识别工具已证明是非常可靠和始终如一的。它已成为支持CA索引输入和最终产品编制的必要的CAS生产工具。中科院化学登记处还发现，在1975年4月8日宾夕法尼亚州费城举行的美国化学学会第169次全国会议上，化学文献分部受到了广泛的关注。
Chemical Abstracts Service (CAS) in its mission of covering the world’s primary chemical and chemical engineering lit-erature has long been heavily involved with handling of information about chemical substances. A particular problem has been the identification of reoccurrences of substances in scientific literature. Such identification is necessaryto assure consistency in the indexes to Chemical Abstracts. These indexes are based ona systematic chemical nomenclature, and the technique used for many years to assure consistency was to name each indexed substance every time it was cited and to file the name alphabetically in an index with its citations. This resulted in a large amount of redundant effort in repeated renamings. To remedy this situation, the CAS Chemical Registry System was developed in the early 1960’s. The main objective was the establishment of a computer-based system to identify chemical substances uniquely on the basis of molecular structure. It was also realized that the CAS Re-gistry Number would provide a machine address that would allow linking of files containing structural information, no-menclature, indexing, and bibliographic information. Moreover, this linking function was seen as a potential general purpose linkage based on substance identification that could eventually involve external files and data banks, primary literature, and other secondary services. The initial and experimental computer-based system, re-ferred to as Registry I, established the viability and validity of the registration concept forfully defined organic chemical substances. Registry I began operating late in 1964. In 1968, the scope of the system was increased as additional classes of substances were handled, and this system, referred to as Registry II, began to be integrated into the CAS indexing operation. The most recent version of the Registry System, Registry III, was placed in operation in 1974 and embodies major adjustments in the Registry records to make the system more effective in its support of the CAS index nomenclature function and the computer-based structureoutput operation through explicit identification of specific ring systems. As its use has been expanded, Registry has proved itself to be eminently reliable and consistent as a substance identification tool. It has become an essential CAS production tool sup-porting CA index input and final product compilation. The CAS Chemical Registry has also found widespread interest t Presented to the Division of Chemical Literature, 169th National Meeting of the American Chemical Society, Philadelphia, Pa., April 8, 1975.* To whom correspondence should be directed.
