Thanks for the puzzle immp!

After basics:
Code:
+---------------+----------------+-----------------+
| 139 169 13569 |  57  1369  2   |  1379 8    4    |
| 7   2   139   |  4   139   8   |  5    139  6    |
| 4   8   13569 |  57  1369 e36  |  1379 2   d139  |
+---------------+----------------+-----------------+
| 2   5   8     |  1-3 7    f39  |  6    4    19   |
| 6   7   19    |  8   5     4   |  139  139  2    |
| 19  3   4     |  16  2     69  |  8    5    7    |
+---------------+----------------+-----------------+
| 5   169 1369  |  2   368   7   |  4    139 c1389 |
| 13  4   7     |  9   38    5   |  2    6   c138  |
| 8   69  2     | a36  4     1   | b39   7    5    |

Then I used the following chain: 3r9c4=r9c7-r78c9=r3c9-r3c6=r4c6 => r4c4 <> 3; stte.
