Check Digit Verification of cas no

The CAS Registry Mumber 2981-98-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,8 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2981-98:
(6*2)+(5*9)+(4*8)+(3*1)+(2*9)+(1*8)=118
118 % 10 = 8
So 2981-98-8 is a valid CAS Registry Number.
