Check Digit Verification of cas no

The CAS Registry Mumber 4282-81-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,8 and 2 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4282-81:
(6*4)+(5*2)+(4*8)+(3*2)+(2*8)+(1*1)=89
89 % 10 = 9
So 4282-81-9 is a valid CAS Registry Number.
