ASP.NET validation control

[bluesource]

Hey I need a regular expression for a validation control on my password field:

Requirements
Must contain 1 digit
Entire password must be 6-10 digits

I have tried this, this ensures 1 digit, but how do I incorporate the length?
^(\w*(?=\w*\d)\w*)$

Any help greatly appreciated.
