Check Digit Verification of cas no

The CAS Registry Mumber 66866-17-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,8,6 and 6 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 66866-17:
(7*6)+(6*6)+(5*8)+(4*6)+(3*6)+(2*1)+(1*7)=169
169 % 10 = 9
So 66866-17-9 is a valid CAS Registry Number.
