A telephone number is of the form pqr- stu- vwxy, where each letter corresponds to a different decimal digit from 0 to 9. The digit in each part are in strictly decreasing order of magnitude, that is : p > q > r, s > t > u and: v > w > x > y.

It is also known that v,w,x and y (in this order) are consecutive odd digits and s, t and u (in this order) are consecutive even digits.

Determine the 3-digit number pqr, given that p+q+r = 9, and p is not zero. (Even digits by definition will include zero digits.)
