Check Digit Verification of cas no

The CAS Registry Mumber 261-79-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,6 and 1 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 261-79:
(5*2)+(4*6)+(3*1)+(2*7)+(1*9)=60
60 % 10 = 0
So 261-79-0 is a valid CAS Registry Number.
