Check Digit Verification of cas no

The CAS Registry Mumber 4909-57-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,0 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4909-57:
(6*4)+(5*9)+(4*0)+(3*9)+(2*5)+(1*7)=113
113 % 10 = 3
So 4909-57-3 is a valid CAS Registry Number.
