Check Digit Verification of cas no

The CAS Registry Mumber 64143-10-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,1,4 and 3 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 64143-10:
(7*6)+(6*4)+(5*1)+(4*4)+(3*3)+(2*1)+(1*0)=98
98 % 10 = 8
So 64143-10-8 is a valid CAS Registry Number.
