Check Digit Verification of cas no

The CAS Registry Mumber 5488-81-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,8 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5488-81:
(6*5)+(5*4)+(4*8)+(3*8)+(2*8)+(1*1)=123
123 % 10 = 3
So 5488-81-3 is a valid CAS Registry Number.
