				Thanks for the puzzle immp!  Here's the grid after basics:
 
 	  | Code: | 	 		  +--------------+---------------+---------------+
 
|  9   178 178 |  3   4    5   | 78    6   2   |
 
|  2   5   378 |  89  6    1   | 3789  4   379 |
 
| e38  4   6   | f89  7    2   | 3589 g589 1   |
 
+--------------+---------------+---------------+
 
|  4   237 379 |  1   23   8   | 579  h579 6   |
 
|  1   78  789 |  45  59   6   | 2     3   479 |
 
|  6   23  5   |  7   23  a49  | 4-9   1   8   |
 
+--------------+---------------+---------------+
 
| d37  13  134 |  2   8   b49  | 6    c7*9 5   |
 
|  5   9   48  |  6   1    7   | 348   2   34  |
 
|  78  6   2   |  45  59   3   | 1     789 479 |
 
+--------------+---------------+---------------+
 
 | 	  
 
Then I used the chain 9r6c6=r7c6-(9=7*)r7c8-(7=3)r7c1-(3=8)r3c1-(8=9)r3c4-(89=5)r3c8-(57*=9)r4c8 => r6c7 <> 9; stte. |

				Nice one Immpy!
 
 
I used the <23> UR in r46c25 to give r4c2 = 7 to solve |
