Insurmountable a difficult puzzle how to solve it

Hello Knigge!

This type of puzzle is called KAKURO.

To solve it is like a butterfly wrote.
The numbers at the bottom left apply to vertical columns and the numbers at the top right apply to horizontal rows.
Only different numbers may be used for each breakdown!
16 e.g .: may (with two boxes) only be formed from 9 + 7 or 7 + 9. But NOT from 8 + 8!

Now to your riddle:

I would start at the top almost on the left.
Here is 30 horizontally. This can only be formed from the numbers 9 + 8 + 7 + 6 = 30. (In any order)
Stand vertically here:
16 (9 + 7) OR (7 + 9) BUT BUT THE 7 is used as we will see in a moment, the 9 comes up.
9 (6 + 2 + 1) because 7 + 1 + 1 is not allowed. SO THE 6 MUST BE UP!
17 (1 + 2 + 3 + 4 + 7) OR (1 + 2 + 3 + 5 + 6) BUT THE 6 HAS ALREADY BEEN USED THE 7 MUST go up!
11 (9 + 2, 8 + 3, 7 + 4, 6 + 5) Here only 8 + 3 remains. The 8 is used at the top.
Now we have above: 9 - 6 - 7 - 8

So slowly everything is broken down.
But you have chosen a very difficult kakuro.
