OK: How about this:
Keep in mind this is hardly bullet proof. You need to also keep in mind a method to detect hash collisions and and a rehash algorithm.
This brings to mind "the old days" circa 1974 writing assemblers for 8080 microprocessors. Symbol "folding" and hashing.
UPDATE: Limiting yourself to four digits may not be very useful if you have a lot of pages that you are trying to index into your database. The wider your hash is the less likely there will be hash collisions.
