我们改善了更新建议模块。申请号码的建议现在包括检查数字。
As a reminder, a check digit is a number associated with an alphanumeric code to ensure its validity. The European, 德国, Chinese, and Brazilian offices use it to check that the application number is correct. The check digit is located at the end of the application number and starts with a dot, e.g: 16813005.2
因此，对于欧洲、德国、中国和巴西的专利，申请号建议用校验码。
Warning: you may get many suggestions on EP, CN, DE and BR patent numbers during the next suggestion updates (next Wednesday). These suggestions will propose you to add the check digit to your application number. We advise you to accept this addition. Indeed, some features like the renewal module require the check digit.
