Strip Numbers

Hey could someone help me out here....

I need to strip numbers from a passed variable

ex. 3899007

all the numbers will have 990 (so that is the 4th, 5th & sixth
numbers... from the right...) I want to keep everything to the left of
the two 9s... is there an easy way to do that????
