Check Digit Verification of cas no

The CAS Registry Mumber 330557-73-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,0,5,5 and 7 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 330557-73:
(8*3)+(7*3)+(6*0)+(5*5)+(4*5)+(3*7)+(2*7)+(1*3)=128
128 % 10 = 8
So 330557-73-8 is a valid CAS Registry Number.
