Z-Ser(Bzl)-O-o-nitrophenylester is a synthetic chemical compound, specifically a derivative of serine, an amino acid. The compound is characterized by the presence of a benzyl (Bzl) group attached to the serine molecule, which protects the hydroxyl group and prevents unwanted side reactions. Additionally, it features an o-nitrophenyl ester group, which is an o-nitrophenol derivative that forms an ester linkage with the serine's carboxyl group. Z-Ser(Bzl)-O-o-nitrophenylester is often used in peptide synthesis and as a substrate for enzyme assays, particularly in the study of proteases and esterases, due to its ability to be selectively cleaved under specific conditions. The o-nitrophenyl group serves as a chromophore, allowing for the easy detection and quantification of enzymatic activity through a color change upon hydrolysis.

Check Digit Verification of cas no

The CAS Registry Mumber 49689-75-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,6,8 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 49689-75:
(7*4)+(6*9)+(5*6)+(4*8)+(3*9)+(2*7)+(1*5)=190
190 % 10 = 0
So 49689-75-0 is a valid CAS Registry Number.
