Thanks for the puzzle immp!

Code:

+-----------------+-------------+----------------+
| 6 7 2 | 3 5 49 | c49 1 8 |
| 9 34 34 | 1 8 6 | 7 5 2 |
| 1 58 58 | 249 7 249 | 3469 39 b46 |
+-----------------+-------------+----------------+
| 7 e356 1 | 8 4 59 | d369 2 a56* |
| 345 3458 9 | 6 2 7 | 1 38 45 |
| f45 2 4568 | 59 3 1 | g469 89 7 |
+-----------------+-------------+----------------+
| 2345 3456 3456 | 245 9 8 | 25 7 1 |
| 8 9 45 | 7 1 245 | 25 6 3 |
| 25 1 7 | 25 6 3 | 8 4 9 |
+-----------------+-------------+----------------+

Then I used the following chain to solve it: 6*r4c9-(6=4)r3c9-(4=9)r1c7-(6*9=3)r4c7-(36*=5)r4c2-(5=4)r6c1-(46*=9)r6c7 contradiction (i.e. 9r16c7) => r4c9 != 6; stte.

| 6 7 2 | 3 5 49 | 49 1 8 |
| 9 34 34 | 1 8 6 | 7 5 2 |

| 345 3458 9 | 6 2 7 | 1 38 45 |
| 45 2 4568 | 5-9 3 1 | 469 a89 7 |
+----------------------+-----------------+------------------+
| 2345 3456 3456 | 245 9 8 | 25 7 1 |
| 8 9 45 | 7 1 245 | 25 6 3 |
| 25 1 7 | 25 6 3 | 8 4 9 |
+----------------------+-----------------+------------------+

(9)r6c8 = (9-3)r3c8 = (3-6)r3c7 = r3c9 - (6=59)r4c96 => - 9r6c4; stte
