7452-28-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7452-28-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,5 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7452-28:
(6*7)+(5*4)+(4*5)+(3*2)+(2*2)+(1*8)=100
100 % 10 = 0
So 7452-28-0 is a valid CAS Registry Number.
