I have a string that I've matched with regex but that same string is commented out with a # sign in front and regex keep matching it which I do not want.

My Regex

BLTY:\w{8}:\w{8}:\w{5}\.\w{7}\.\w{1}\.\w{3}\/\w{3}\/.*\(\w{4}\)

String

BLTY:ENCQ0000:SERVER:TEMP.PPMQ8FE.Y.323/TCP/gtg23.dev.pmt.com(3213)-> only match this
#BLTY:ENCQ0000:SERVER:TEMP.PPMQ8FE.Y.323/TCP/gtg23.dev.pmt.com(3213) -> I dont want to match this

Tried

^[BLTY:\w{8}:\w{8}:\w{5}\.\w{7}\.\w{1}\.\w{3}\/\w{3}\/.*\(\w{4}\)]

^BLTY:\w{8}:\w{8}:\w{5}\.\w{7}\.\w{1}\.\w{3}\/\w{3}\/.*\(\w{4}\)

(?!#)BLTY:\w{8}:\w{8}:\w{5}\.\w{7}\.\w{1}\.\w{3}\/\w{3}\/.*\(\w{4}\)

Also if there's a less verbose/optimized way of writing this regex Im open to hear

No need using lookaheads:

^BLTY(?::\w+){3}(?:\.\w+){3}/.*\(\d+\)$

See regex proof.
