Need help using Regex to parse street addresses

Question

Let me start off by stating three things:
I suck at regex,
I've googled this and didn't come up with an answer, and
I'm on ColdFusion 10
I have a form with an autocomplete input that allows a user to enter street addresses (either in full like "123 Main St, Mayberry" or in part like "123 Main St" or "Main St" or "Main St, Mayberry".  I need to tell if the user has provided a street number or not at the beginning of the value they enter into the input.  I'm trying to test the input value with this code:
<cfif ReFind("^([0-9]{1-5})",q)>
     <!--- address starts with a number --->
<cfelse>
     <!--- address doesn't start with a number --->
</cfelse>
q is the input value being passed into my code from the autocomplete function.
x should be either 0 (if the input value doesn't start with a number) or a positive integer (if the input value does start with a number).
Basically, I just need to know if the input value starts with one to five digits.
I suppose I could just do something like:
<cfif Val(q)>
Am I better off using a regex, and if so, what am I doing wrong with the one I've tried?

Oh man do I feel stupid!  I read the Adobe docs several times, and understood I needed a comma there, but I had a brain fart when I actually typed my code.  Thanks for the minor *headslap*!
I had tried it without the parantheses before, and had added them when trying to troubleshoot.  I'll remove them from my working code.
And I will check out your blog series on Regex.
