Regular expressions might be regular but not 
exactly all the same. For instance PERL has it's 
own schema for regular exxpressions different 
from, say, grep.

The above looks like a PERL expression, but 
probably won't work as expected in grep.

What regular expression tool are you using? Have 
you tried matching w/o the ^ and %?

How about [SACN]\d{1,2}-\d {1,6}
