Check Digit Verification of cas no

The CAS Registry Mumber 21818-23-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,8,1 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21818-23:
(7*2)+(6*1)+(5*8)+(4*1)+(3*8)+(2*2)+(1*3)=95
95 % 10 = 5
So 21818-23-5 is a valid CAS Registry Number.
