I've submitted my answer now.
For anyone looking to compare answers, the MD5 hash for the sum of my accross clues is e8938a2d47a3f3c420478335278eb2e9. Another interesting point is that the answer is a semiprime equal to 5 * p16.

My answer matches your 5XP16
For MD5....I tried 3 different MD5 generators and got 3 different answers but 1 matched yours. I think we match!!! I have to acknowledge that my son helped a ton and had the "BIG" calculator.

Ah, no need for that. All of these fit well inside a 64 bit int, you can get 19 digits in those.
Sadly doable these days in a couple of hours with a 1080 Ti.
