Check Digit Verification of cas no

The CAS Registry Mumber 61931-52-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,9,3 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 61931-52:
(7*6)+(6*1)+(5*9)+(4*3)+(3*1)+(2*5)+(1*2)=120
120 % 10 = 0
So 61931-52-0 is a valid CAS Registry Number.
