optimize Powershell RegEx match

Question

I'd like to have a RegEx in Powershell which matches following expressions:

MusMax / musmax
MusMax1 / musmax1

But it should not match with:

tMusMax / tmusmax
tMusMax1 / tmusmax1
itMusMax / itmusmax
itMusMax1 / itmusmax1

The code that I have until now is following:

((?=.*[a-zA-Z])(?=.*\d).{6,7})

My Problem is that this RegEx only matches to the expressions with a digit in the last place, but the digit is optional so it should not match only these.

Thanks for any help!

You haven't defined what your regex should match very well. Can you write one sentence of plain English for that? — Tomalak

Could it be as simple as:

\b[a-zA-Z]{6}\d?\b

(My interpretation of your samples was "Whole words of six ASCII characters that end in an optional additional digit.")

Thank Tomalak for the quick answer! Your Interpretation was right and so was your RegEx.
