Check Digit Verification of cas no

The CAS Registry Mumber 51128-71-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,1,2 and 8 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 51128-71:
(7*5)+(6*1)+(5*1)+(4*2)+(3*8)+(2*7)+(1*1)=93
93 % 10 = 3
So 51128-71-3 is a valid CAS Registry Number.
