Dúvia match perl

I need a perl help for a regular expression match ... But it's the reverse of what usually happens ....

I need to do a match on the next one.

I have the number "(0003 [6-9]) (.00041).: : 30/30 ", the delimiter is the colon, however, I needed to test if a given number will match in these columns ... Anyway I needed to know if there is a way to test a number on a regular expression.

Thank you.
