Check Digit Verification of cas no

The CAS Registry Mumber 67335-20-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,3,3 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 67335-20:
(7*6)+(6*7)+(5*3)+(4*3)+(3*5)+(2*2)+(1*0)=130
130 % 10 = 0
So 67335-20-0 is a valid CAS Registry Number.
