Check Digit Verification of cas no

The CAS Registry Mumber 81023-81-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,0,2 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 81023-81:
(7*8)+(6*1)+(5*0)+(4*2)+(3*3)+(2*8)+(1*1)=96
96 % 10 = 6
So 81023-81-6 is a valid CAS Registry Number.
