Check Digit Verification of cas no

The CAS Registry Mumber 6471-51-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,7 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6471-51:
(6*6)+(5*4)+(4*7)+(3*1)+(2*5)+(1*1)=98
98 % 10 = 8
So 6471-51-8 is a valid CAS Registry Number.
