DaVinci
DAVI fifth letter is the check/change 1N3
13 is a Jewish Holy Number drop 1 level
to the D 0D3
DAVID (King David ???)
now C & I are 8 and 2 which is 10 you dropped to 03 from 13 c & I bring you back up to 13 for the other 10 to verify the code.
This might be why the works of DaVinci where so broadly accepted and his insight to future devices was so intact.
Take this in the spirit of Fun and the One-Der of possibilities.
God Bless
