Check Digit Verification of cas no

The CAS Registry Mumber 28149-61-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,1,4 and 9 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 28149-61:
(7*2)+(6*8)+(5*1)+(4*4)+(3*9)+(2*6)+(1*1)=123
123 % 10 = 3
So 28149-61-3 is a valid CAS Registry Number.
