Check Digit Verification of cas no

The CAS Registry Mumber 81766-18-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,7,6 and 6 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 81766-18:
(7*8)+(6*1)+(5*7)+(4*6)+(3*6)+(2*1)+(1*8)=149
149 % 10 = 9
So 81766-18-9 is a valid CAS Registry Number.
