Check Digit Verification of cas no

The CAS Registry Mumber 2957-05-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,5 and 7 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2957-05:
(6*2)+(5*9)+(4*5)+(3*7)+(2*0)+(1*5)=103
103 % 10 = 3
So 2957-05-3 is a valid CAS Registry Number.
