Check Digit Verification of cas no

The CAS Registry Mumber 218443-23-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,8,4,4 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 218443-23:
(8*2)+(7*1)+(6*8)+(5*4)+(4*4)+(3*3)+(2*2)+(1*3)=123
123 % 10 = 3
So 218443-23-3 is a valid CAS Registry Number.
