Check Digit Verification of cas no

The CAS Registry Mumber 4211-99-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,1 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4211-99:
(6*4)+(5*2)+(4*1)+(3*1)+(2*9)+(1*9)=68
68 % 10 = 8
So 4211-99-8 is a valid CAS Registry Number.
