Check Digit Verification of cas no

The CAS Registry Mumber 32398-68-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,3,9 and 8 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 32398-68:
(7*3)+(6*2)+(5*3)+(4*9)+(3*8)+(2*6)+(1*8)=128
128 % 10 = 8
So 32398-68-8 is a valid CAS Registry Number.
