Check Digit Verification of cas no

The CAS Registry Mumber 4943-09-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,4 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4943-09:
(6*4)+(5*9)+(4*4)+(3*3)+(2*0)+(1*9)=103
103 % 10 = 3
So 4943-09-3 is a valid CAS Registry Number.
