Check Digit Verification of cas no

The CAS Registry Mumber 4941-84-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,4 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4941-84:
(6*4)+(5*9)+(4*4)+(3*1)+(2*8)+(1*4)=108
108 % 10 = 8
So 4941-84-8 is a valid CAS Registry Number.
