Check Digit Verification of cas no

The CAS Registry Mumber 4657-08-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,5 and 7 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4657-08:
(6*4)+(5*6)+(4*5)+(3*7)+(2*0)+(1*8)=103
103 % 10 = 3
So 4657-08-3 is a valid CAS Registry Number.
