Check Digit Verification of cas no

The CAS Registry Mumber 21681-61-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,6,8 and 1 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 21681-61:
(7*2)+(6*1)+(5*6)+(4*8)+(3*1)+(2*6)+(1*1)=98
98 % 10 = 8
So 21681-61-8 is a valid CAS Registry Number.
