Check Digit Verification of cas no

The CAS Registry Mumber 159116-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,1,1 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 159116-91:
(8*1)+(7*5)+(6*9)+(5*1)+(4*1)+(3*6)+(2*9)+(1*1)=143
143 % 10 = 3
So 159116-91-3 is a valid CAS Registry Number.
