How to correctly compose a regular expression in Advanced Module Manager?

Question

Joomla

Good afternoon. Installed the Advanced Module Manager component in order to hide the module on certain pages. I decided to hide the module ONLY on the link, for example, cat.honestks.ru/index.php/123. But I have more content at cat.honestks.ru/index.php/123/321, and the fact is that the module is not displayed on all pages where "123" is present.
The component can use regular expressions, but I can't figure out how to compose an expression so that the module is hidden only on one page ( cat.honestks.ru/index.php/123), and the module is displayed on the rest ( cat.honestks.ru/ index.php/123/321, cat.honestks.ru/index.php/123/test, cat.honestks.ru/index.php/123/novost2)
