I verfied on gskinner online regular expression complier and this is pretty neat capture Just try this (?:ABC)  : which mean this expression groups multiple tokens together without creating a capturing group. This allows you to apply quantifiers to the full group.

 

So in your case -

 

 Pattern would be - (?:123)

 

Tested and Verified on Gskinner - check and verify
