Check Digit Verification of cas no

The CAS Registry Mumber 6660-66-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,6 and 0 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6660-66:
(6*6)+(5*6)+(4*6)+(3*0)+(2*6)+(1*6)=108
108 % 10 = 8
So 6660-66-8 is a valid CAS Registry Number.
