Check Digit Verification of cas no

The CAS Registry Mumber 4118-07-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,1 and 8 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4118-07:
(6*4)+(5*1)+(4*1)+(3*8)+(2*0)+(1*7)=64
64 % 10 = 4
So 4118-07-4 is a valid CAS Registry Number.
