4273-28-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4273-28-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,7 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4273-28:
(6*4)+(5*2)+(4*7)+(3*3)+(2*2)+(1*8)=83
83 % 10 = 3
So 4273-28-3 is a valid CAS Registry Number.
