Check Digit Verification of cas no

The CAS Registry Mumber 128966-22-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,9,6 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 128966-22:
(8*1)+(7*2)+(6*8)+(5*9)+(4*6)+(3*6)+(2*2)+(1*2)=163
163 % 10 = 3
So 128966-22-3 is a valid CAS Registry Number.
