My solution was similar to Tom's.
Code:
+---------------+-----------------+---------------------+
| 146 1359 7    | b49   1269 a29* |  8      1235  f35   |
| 2   1589 158  |  7   d189   3   |  4     e15     6    |
| 146 138  1368 | c48   1268  5   | g23     9      7    |
+---------------+-----------------+---------------------+
| 9   7    26   |  3    5     1   |  26     4      8    |
| 16  138  1368 |  2    4     7   |  3569   356    359  |
| 5   4    23   |  89   89    6   |  237    237    1    |
+---------------+-----------------+---------------------+
| 8   2    45   |  1    379   49  |  35679  3567   3459 |
| 3   15   145  |  6    79    489 |  579    578    2    |
| 7   6    9    |  5    23    248 |  1      38     34   |
+---------------+-----------------+---------------------+

(2=9*)r1c6 - (9=4)r1c4 - (4=8)r3c4 - (89*=1)r2c5 - (1=5)r2c8 - (5=3)r1c9 - (3=2)r3c7 => r1c8 <> 2; stte.

Very good dongrave, and of course your chain shows that r3c5 <> 2 as well!
