Why use an algorithm when you've got a gigahertz CPU and a list
comprehension?


import string
print [ (x,y,x*y) for x in range(1000) for y in range(100)
        if map( lambda a: string.count(str(x)+str(y)+str(x*y),a),
        map(str,range(10)))==[1]*10 ]


(yes, this goes directly into the python hall of shame together with
my operator module)
