Check Digit Verification of cas no

The CAS Registry Mumber 98299-14-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,2,9 and 9 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 98299-14:
(7*9)+(6*8)+(5*2)+(4*9)+(3*9)+(2*1)+(1*4)=190
190 % 10 = 0
So 98299-14-0 is a valid CAS Registry Number.
