Check Digit Verification of cas no

The CAS Registry Mumber 4840-84-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,4 and 0 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4840-84:
(6*4)+(5*8)+(4*4)+(3*0)+(2*8)+(1*4)=100
100 % 10 = 0
So 4840-84-0 is a valid CAS Registry Number.
