Nα-Carbobenzoxy-Nδ-acetyl-L-ornithin-p-nitrophenylester is a complex organic compound that serves as a synthetic substrate for the enzyme arginase. Nα-Carbobenzoxy-Nδ-acetyl-L-ornithin-p-nitrophenylester is designed to mimic the natural substrate of arginase, which is L-arginine. The carbobenzoxy (Cbz) group is a protecting group used in peptide synthesis to prevent unwanted side reactions, while the acetyl (Ac) group is another protecting group that stabilizes the molecule. The p-nitrophenylester (pNP) group is a chromophore that changes color upon hydrolysis, allowing for the quantification of enzyme activity. This substrate is particularly useful in biochemical research and drug development, as it allows for the study of arginase activity and the effects of potential inhibitors or activators on this enzyme.

3883-21-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3883-21-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,8 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3883-21:
(6*3)+(5*8)+(4*8)+(3*3)+(2*2)+(1*1)=104
104 % 10 = 4
So 3883-21-4 is a valid CAS Registry Number.
