Check Digit Verification of cas no

The CAS Registry Mumber 169692-31-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,6,9 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 169692-31:
(8*1)+(7*6)+(6*9)+(5*6)+(4*9)+(3*2)+(2*3)+(1*1)=183
183 % 10 = 3
So 169692-31-3 is a valid CAS Registry Number.
