5111-43-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5111-43-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,1 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5111-43:
(6*5)+(5*1)+(4*1)+(3*1)+(2*4)+(1*3)=53
53 % 10 = 3
So 5111-43-3 is a valid CAS Registry Number.
