Check Digit Verification of cas no

The CAS Registry Mumber 67637-74-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,6,3 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 67637-74:
(7*6)+(6*7)+(5*6)+(4*3)+(3*7)+(2*7)+(1*4)=165
165 % 10 = 5
So 67637-74-5 is a valid CAS Registry Number.
