Entering the 2 and 3 in row three and four (check: target number 6x) nails down the 1 in column four which, in turn, gives us the 3 in row one and the 1 in row two. Just checking the target number for that cage, 3 x 1 x 1 = 3. Voila! The puzzle is solved. No numbers repeat in any row or column and all the target numbers have been met.
