Check Digit Verification of cas no

The CAS Registry Mumber 330785-87-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,0,7,8 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 330785-87:
(8*3)+(7*3)+(6*0)+(5*7)+(4*8)+(3*5)+(2*8)+(1*7)=150
150 % 10 = 0
So 330785-87-0 is a valid CAS Registry Number.
