Check Digit Verification of cas no

The CAS Registry Mumber 203063-33-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,0,6 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 203063-33:
(8*2)+(7*0)+(6*3)+(5*0)+(4*6)+(3*3)+(2*3)+(1*3)=76
76 % 10 = 6
So 203063-33-6 is a valid CAS Registry Number.
