Check Digit Verification of cas no

The CAS Registry Mumber 4660-78-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,6 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4660-78:
(6*4)+(5*6)+(4*6)+(3*0)+(2*7)+(1*8)=100
100 % 10 = 0
So 4660-78-0 is a valid CAS Registry Number.
