Z-Gly-Val-OBzl, also known as Z-Glycine-Valine-Benzyl Ester, is a tripeptide derivative featuring a benzyl ester protecting group. It consists of three amino acids: glycine (Gly), valine (Val), and a terminal glycine residue with a benzyl ester (OBzl) protecting group. This chemical is commonly used in peptide synthesis and organic chemistry as a building block for the formation of larger peptides and proteins. The benzyl ester group is crucial for protecting the carboxylic acid functionality during peptide bond formation, allowing for selective deprotection and subsequent coupling reactions in peptide synthesis. Z-Gly-Val-OBzl is a valuable tool in the development of pharmaceuticals, bioactive peptides, and other related applications.

Check Digit Verification of cas no

The CAS Registry Mumber 57294-40-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,2,9 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 57294-40:
(7*5)+(6*7)+(5*2)+(4*9)+(3*4)+(2*4)+(1*0)=143
143 % 10 = 3
So 57294-40-3 is a valid CAS Registry Number.

A KINETIC STUDY OF PHOSPHINIC CARBOXYLIC MIXED ANHYDRIDES

Ramage, Robert,Atrash, Butrus,Hopton, David,Parrott, Maxwell J.

, p. 1617 - 1622 (2007/10/02)

Using 32.4 MHz (31)P n.m.r. spectroscopy, disproportionation of a series of phosphinic carboxylic mixed anhydrides derived from protected α-amino acids has been studied both as a function of the substituents at phosphorus and structure of the α-amino acid being activated.It was found that the rates of disproportionation were insignificant from a preparative aspect compared with aminolysis at 0 deg C.
