Check Digit Verification of cas no

The CAS Registry Mumber 7357-71-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,5 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7357-71:
(6*7)+(5*3)+(4*5)+(3*7)+(2*7)+(1*1)=113
113 % 10 = 3
So 7357-71-3 is a valid CAS Registry Number.
