Check Digit Verification of cas no

The CAS Registry Mumber 18110-21-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,1,1 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 18110-21:
(7*1)+(6*8)+(5*1)+(4*1)+(3*0)+(2*2)+(1*1)=69
69 % 10 = 9
So 18110-21-9 is a valid CAS Registry Number.
