答案（中文）
根据 REACH 附件 II 第 1.1 点和第 3.2.4 点的规定，分销商/配方师可以在安全数据表中截取其供应商注册号（省略后四位数字）。如果注册人联合提交注册，则特定物质的注册号前半部分相同。因此，只需包含一个截取的注册号。但是，如果注册人在联合提交时未注册，则该注册号不同。因此，所有相关（截取的）注册号都应在安全数据表中注明。
Answer (EN)
Distributors/formulators can truncate the registration number (omit the last four digits) of their suppliers' registration numbers in the SDS in accordance with points 1.1 and 3.2.4 of Annex II of REACH.
The first part of the registration number is the same for a given substance if the registrants have jointly submitted their registrations. Therefore, only one truncated registration number needs to be included. However, if a registrant has not registered in the context of the joint submission, this registration number is different. Therefore, all relevant (truncated) registration numbers should be mentioned in the SDS.
