Check Digit Verification of cas no

The CAS Registry Mumber 7257-50-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,5 and 7 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7257-50:
(6*7)+(5*2)+(4*5)+(3*7)+(2*5)+(1*0)=103
103 % 10 = 3
So 7257-50-3 is a valid CAS Registry Number.
