Check Digit Verification of cas no

The CAS Registry Mumber 81819-98-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,8,1 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 81819-98:
(7*8)+(6*1)+(5*8)+(4*1)+(3*9)+(2*9)+(1*8)=159
159 % 10 = 9
So 81819-98-9 is a valid CAS Registry Number.
