5428-19-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5428-19-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,2 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5428-19:
(6*5)+(5*4)+(4*2)+(3*8)+(2*1)+(1*9)=93
93 % 10 = 3
So 5428-19-3 is a valid CAS Registry Number.
