131326-41-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 131326-41-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,3,2 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 131326-41:
(8*1)+(7*3)+(6*1)+(5*3)+(4*2)+(3*6)+(2*4)+(1*1)=85
85 % 10 = 5
So 131326-41-5 is a valid CAS Registry Number.

PEPTIDE BOND FORMATION USING AN ENZYME MIMICKING APPROACH

Gennari, Cesare,Molinari, Francesco,Piarulli, Umberto,Bartoletti, Marcella

, p. 7289 - 7300 (2007/10/02)

A man-made enzyme-model based on a concerted proton transfer step (bifunctional catalysis) which mimics the corresponding step in non-ribosomal peptide synthesis was developed.Important features of the model are the following: (a) a bifunctional acid-base catalyst for the thiolester aminolysis rate acceleration, (b) two thiol-containing arms mimicking the "swinging arms" of the enzyme, and (c) symmetry elements so that the process can be iterated with consequent formation of the polypeptide chain.Peptide bond formation was obtained by intramolecularly catalyzed thiolester aminolysis to give 5 in 80percent isolated yield (Scheme IV, V) and with at least a 103-fold rate acceleration in comparison with the corresponding non catalyzed process (4 -> 6)(Scheme IV, Table 1).The reaction is also 4-20 times faster than the analogous process 4 -> 6 run in the presence of 0.1M external catalyst (Et3N-ButCOOH or 2-Pyridone).Important structural and reaction parameters are discussed.A second intramolecular aminolysis reaction gave tripeptide 8 in lower yield (35percent) because of higher steric congestion in the transition state.
