25107-53-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 25107-53-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,1,0 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 25107-53:
(7*2)+(6*5)+(5*1)+(4*0)+(3*7)+(2*5)+(1*3)=83
83 % 10 = 3
So 25107-53-3 is a valid CAS Registry Number.
