This contract is for the purpose of obtaining the following Chemical Abstracts Service (CAS) information products: (1) CAS Registry Services, (2) CHEMLINE Support, and (3) Special Studies and Programming Efforts. (1) CAS Registry Services: NLM submits to CAS the files of substance data which have been obtained from a number of sources. The major source comes from new chemicals indexed for the MEDLINE database, MESH chemical records for which there are no CAS Registry Numbers are submitted to CAS for name match and then chemist review in order to add this data to MESH and MEDLINE. NLM also supports the addition of CAS Registry Numbers to other files such as the Registry of Toxic Effects of Chemical Substances (RTECS), which is available online in the TOXNET system. (2) CHEMLINE Support: CAS maintains the CHEMLINE profile and keeps it up to date by the addition of and/or deletion of substance records as they are identified by NLM for incorporation into the file, or identified by CAS as being inaccurate. The registration process for CHEMLINE is similar to the service described above, but goes further by helping NLM to main maintain CHEMLINE as an accurate and up-to-date file. (3) Special Studies and Programming Efforts: As changes to the CHEMLINE Maintenance System or other services to NLM become necessary, CAS provides systems analysis and programming for necessary modifications to these programs.

本合同旨在获得以下化学品 摘要服务（CAS）信息产品：（1）CAS注册服务， (2)CHEMLINE支持，和（3）特别研究和规划工作。 (1)CAS注册服务：NLM向CAS提交物质数据文件 其已经从多个来源获得。 主要来源于 来自MEDLINE数据库索引的新化学品，MESH化学记录 没有CAS登记号的，提交给CAS进行命名 匹配，然后化学家审查，以便将该数据添加到MESH中， MEDLINE。NLM还支持将CAS登记号添加到其他 化学物质毒性作用登记册等文件 （RTECS），该系统可在TOXNET系统中在线查阅。 (2)CHEMLINE支持：CAS维护CHEMLINE配置文件并保持其正常运行 通过添加和/或删除物质记录， 由NLM识别以纳入文件，或由 我认为是不准确的。 CHEMLINE的注册流程类似 到上述服务，但更进一步，帮助NLM主要 保持CHEMLINE作为一个准确和最新的文件。 (3)特别研究和方案编制工作：作为化学品生产线的变化 如果NLM需要维护系统或其他服务，CAS提供 系统分析和编程，以进行必要的修改， 程序.
