Check Digit Verification of cas no

The CAS Registry Mumber 4933-40-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,3 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4933-40:
(6*4)+(5*9)+(4*3)+(3*3)+(2*4)+(1*0)=98
98 % 10 = 8
So 4933-40-8 is a valid CAS Registry Number.
