Check Digit Verification of cas no

The CAS Registry Mumber 216018-80-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,6,0,1 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 216018-80:
(8*2)+(7*1)+(6*6)+(5*0)+(4*1)+(3*8)+(2*8)+(1*0)=103
103 % 10 = 3
So 216018-80-3 is a valid CAS Registry Number.
