Check Digit Verification of cas no

The CAS Registry Mumber 77213-22-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,2,1 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 77213-22:
(7*7)+(6*7)+(5*2)+(4*1)+(3*3)+(2*2)+(1*2)=120
120 % 10 = 0
So 77213-22-0 is a valid CAS Registry Number.
