Sum Hell

Normal Sudoku rules apply.
Orange Line: An orange line indicates the sum of all digits that are not on an orange line in this row/column (row for horizontal lines and column for vertical ones). The sum is read as the concatenation of the 2 digits on the line, in some order.
Arrow: Digits along an arrow sum to the number in the attached circle.
Disjoint Groups: Cells that appear in the same position relative to their 3x3 box must not contain the same digit. For example, if there is a 3 in r1c1, then you can't have a 3 in r1c4, r1c7, r4c1, r4c4, r4c7, r7c1, r7c4 and r7c7.
Solution code: Row 7 from left to right

The first half of the puzzle is easy if you take the time to do the math (and almost impossible if you don't). The second half is a great exercise in disjoint sets. Overall no more than 3*. A really nice puzzle

It was easy. After a bit of math at the beginning it was a joy and solved itself pretty easily. Nice idea!
Edit: I want to encourage people! This is much easier and nicer than it looks!
