That was hard, but with a few notes on the side with possible sums I could piece it together. Very nice construction. Thanks!

I went astray a few times, including once that gave me a lot of the right digits for the wrong reason when I was sure I knew what C was by way of row 9 even though I did not. Ultimately though, super clever, this here puzzle. Thank you!
