I don't know if I made a mistake but I got two solutions:
Code:
.----.----.----.----.----.----.----.----.----.
| 5 | 9 | 7 | 1 | 8 | 2 | 34 | 34 | 6 |
:----+----+----'----+----+----'----+----+----:
| 4 | 2 | 6 3 | 5 | 9 1 | 7 | 8 |
:----+----+----.----+----'----.----+----+----:
| 3 | 1 | 8 | 6 | 4 7 | 5 | 2 | 9 |
:----+----+----+----+----.----+----+----+----:
| 8 | 5 | 9 | 4 | 7 | 3 | 6 | 1 | 2 |
| :----: :----+----+----+----+----+----:
| 7 | 6 | 2 | 8 | 1 | 5 | 49 | 49 | 3 |
