Check Digit Verification of cas no

The CAS Registry Mumber 81399-98-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,3,9 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 81399-98:
(7*8)+(6*1)+(5*3)+(4*9)+(3*9)+(2*9)+(1*8)=166
166 % 10 = 6
So 81399-98-6 is a valid CAS Registry Number.
