是否可以在 SDS 中使用仅具有 CAS 编号或没有数字标识符的物质的列表编号？

Can list numbers assigned to substances with only a CAS Number or without a numerical identifier be used in the SDS?

例如，仅具有 CAS 编号或没有任何数字标识符的预注册、查询或通知 C&L 清单的物质将自动分配一个列表编号。与 EINECS、ELINCS 和 NLP 条目不同，列表编号和列表清单不是基于法律行为或要求，并且未在欧盟官方公报上公布。因此，列表编号与 EC 编号的意义不同，只有数字格式相同。最重要的是，绝大多数列表编号及其关联的物质标识从未经过正确性、有效性检查，或是否遵守了 REACH 物质识别和命名指南中概述的惯例。因此，建议业界不要在其文件中使用列表编号。但是，当供应商希望在文件（例如安全数据表）中包含列表编号时，应明确指出该编号不是 EC 编号，不具有法律意义。

Substances e.g. pre-registered, inquired or notified to the C&L Inventory with only a CAS number or without any numerical identifier are automatically assigned a list number. In contrast to the EINECS, ELINCS and NLP entries, the list numbers and the list inventory are not based on a legal act or requirement, and they have not been published in the Official Journal of the European Union. Therefore, the list numbers do not have the same significance as EC numbers but have only the numerical format in common. Most importantly, the vast majority of list numbers and their connected substance identification have never been checked for correctness, validity or whether the conventions outlined in the Guidance for Identification and naming of substances under REACH have been kept. Therefore, industry is advised not to use list numbers in their documents. However, when a supplier wishes to include a list number on a document, e.g. Safety Data Sheet, it shall be clearly indicated that this number is not an EC number and has no legal significance.
