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.

| 25      1       7    | 25     6    3   | 8       4     9  |
+----------------------+-----------------+------------------+

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