Check Digit Verification of cas no

The CAS Registry Mumber 216063-35-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,6,0,6 and 3 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 216063-35:
(8*2)+(7*1)+(6*6)+(5*0)+(4*6)+(3*3)+(2*3)+(1*5)=103
103 % 10 = 3
So 216063-35-3 is a valid CAS Registry Number.
