You are using the asterisk as a "wild card".

You want the sum of the digit values to be an integer product of 9.

x instead of *,

29%3C=x%2B29%3C=38;
You know that neither of the limits is a product of 9, so look within the limits for the very few products of 9. Checking with the basic multiplication facts, 36 is that number.

x%2B29=36
x=36-29
highlight%28x=7%29-----------this is the missing digit.

6357672 is divisible by 9.
