Check Digit Verification of cas no

The CAS Registry Mumber 131366-19-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,3,6 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 131366-19:
(8*1)+(7*3)+(6*1)+(5*3)+(4*6)+(3*6)+(2*1)+(1*9)=103
103 % 10 = 3
So 131366-19-3 is a valid CAS Registry Number.
