I wrote a computer program to solve this:


6 1 2 5 4 3 7 # 8 9
1 2 3 4 # 5 9 6 7 8
2 4 5 9 1 7 3 8 # 6
3 5 6 2 7 8 # 1 9 4
4 7 # 8 9 1 6 3 2 5
7 8 9 # 2 6 4 5 1 3
5 # 7 3 8 9 1 4 6 2
9 6 8 7 3 # 5 2 4 1
8 9 1 6 5 4 2 7 3 #
# 3 4 1 6 2 8 9 5 7


The program quits when it finds a solution so I don't know if there are others. By coincidence, the program ran about 20 times faster than would be expected just because by fantastic luck, the first two guesses it made were correct. If I had moved vertically down the matrix instead of horizontally across, it would have run even faster as the first four guesses would have been correct.
