Check Digit Verification of cas no

The CAS Registry Mumber 71809-19-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,8,0 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 71809-19:
(7*7)+(6*1)+(5*8)+(4*0)+(3*9)+(2*1)+(1*9)=133
133 % 10 = 3
So 71809-19-3 is a valid CAS Registry Number.
