What I meant:

Solving the ABC*CDE=EAIAGG (forget the partial products) yields two distinct solutions (Charlie's or any similar program):

a) 754*493=371722
b) 516*693=357588

Compare with the given numbers (forget the partial products):

c) 617*702=357599 

Only b) solution has one  digit (digit "1") invariant while coded.
