Enigma Number 1690

Dolly the sheep

Dolly was the name given to the first cloned sheep at the UK’s Roslin Institute in 1996. The letters in the diagram represent, in some order, the numbers 1 to 16 forming a magic square where each row, column and main diagonal have the same sum. The letters of the word “clone”, and letters not within the square, have their values according to a=1, b=2 etc. but other letters within the square may or may not.

What is the sum d+o+l+l+y?
