Check Digit Verification of cas no

The CAS Registry Mumber 98321-21-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,3,2 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 98321-21:
(7*9)+(6*8)+(5*3)+(4*2)+(3*1)+(2*2)+(1*1)=142
142 % 10 = 2
So 98321-21-2 is a valid CAS Registry Number.
