Check Digit Verification of cas no

The CAS Registry Mumber 6946-21-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,4 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6946-21:
(6*6)+(5*9)+(4*4)+(3*6)+(2*2)+(1*1)=120
120 % 10 = 0
So 6946-21-0 is a valid CAS Registry Number.
