Little Killer Sandwiches

Normal anti-king* Sudoku rules apply: place the digits 1-9 once each in every row, column and 3×3 region so that no digit re-appears in any of its surrounding cells, not even diagonally.
The clues outside the grid all have two meanings: they give the sum of the diagonals indicated by the arrows, AND they give the sum of digits "sandwiched" between the numbers 1 and 9 in the clue's row or column. (The latter doesn't apply to the clue in the top left corner as it doesn't see any row or column directly.)
*(Anti-king = cells which are a chess king's move away cannot contain identical digits.)

This might be the hardest puzzle I've created to date.
Lösungscode: Digits in row 5 followed by digits in column 7; a total of 18 digits with no spaces or other symbols in between.

This puzzle is nice! Some parts are tricky though, and the use of 36 clue is brilliant!
