Check Digit Verification of cas no

The CAS Registry Mumber 161870-09-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,8,7 and 0 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 161870-09:
(8*1)+(7*6)+(6*1)+(5*8)+(4*7)+(3*0)+(2*0)+(1*9)=133
133 % 10 = 3
So 161870-09-3 is a valid CAS Registry Number.
