25328-53-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 25328-53-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,3,2 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 25328-53:
(7*2)+(6*5)+(5*3)+(4*2)+(3*8)+(2*5)+(1*3)=104
104 % 10 = 4
So 25328-53-4 is a valid CAS Registry Number.
