In the multiplication given below, all the digits, except one, were consistently replaced by another digit:

    617 
*   702 
_______
   1639 
  3733 
 2807  
__________  
 265699

Find the substitution code and restore the original multiplication.

Not true.  I wasn't ignoring the permutated digits.  In fact I checked back a few times to see if I had come across the duplicated digit.

For example when I found my C was 6 I checked back to see that your original puzzle had a 7.  I just didn't want to write statements like 7=6.
