Check Digit Verification of cas no

The CAS Registry Mumber 74785-26-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,7,8 and 5 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 74785-26:
(7*7)+(6*4)+(5*7)+(4*8)+(3*5)+(2*2)+(1*6)=165
165 % 10 = 5
So 74785-26-5 is a valid CAS Registry Number.
