Check Digit Verification of cas no

The CAS Registry Mumber 330675-44-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,0,6,7 and 5 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 330675-44:
(8*3)+(7*3)+(6*0)+(5*6)+(4*7)+(3*5)+(2*4)+(1*4)=130
130 % 10 = 0
So 330675-44-0 is a valid CAS Registry Number.
