Check Digit Verification of cas no

The CAS Registry Mumber 33355-69-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,3,5 and 5 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 33355-69:
(7*3)+(6*3)+(5*3)+(4*5)+(3*5)+(2*6)+(1*9)=110
110 % 10 = 0
So 33355-69-0 is a valid CAS Registry Number.
