There is a four digit number such that when multiplied by a single digit produces another four digit number i.e. "ABCD"*E="FGHI " (the letters between the quotation signs designate a concatenation, not the product).

The letters represent 9 non-zero distinct digits.

Find the two existing solutions to this 9-digit problem.

(In reply to solution by Jer)

IMHO - timewise it was the most effective way.
