Check Digit Verification of cas no

The CAS Registry Mumber 4320-81-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,2 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4320-81:
(6*4)+(5*3)+(4*2)+(3*0)+(2*8)+(1*1)=64
64 % 10 = 4
So 4320-81-4 is a valid CAS Registry Number.
