142955-51-9 Usage
General Description
BOC-PHE-N-CARBOXYANHYDRIDE, also known as Boc-phenylalanine N-carboxyanhydride, is a chemical compound used in peptide synthesis. It is a derivative of the amino acid phenylalanine and is commonly used as a coupling reagent to form peptide bonds during the solid-phase synthesis of peptides. BOC-PHE-N-CARBOXYANHYDRIDE acts as a protecting group for the side chain of phenylalanine, allowing for selective deprotection and coupling reactions. It is a valuable tool in the production of peptides for use in pharmaceuticals, biotechnology, and research.
Check Digit Verification of cas no
The CAS Registry Mumber 142955-51-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,9,5 and 5 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 142955-51:
(8*1)+(7*4)+(6*2)+(5*9)+(4*5)+(3*5)+(2*5)+(1*1)=139
139 % 10 = 9
So 142955-51-9 is a valid CAS Registry Number.

Activation of N,N-bis-Boc or N-Boc N-Z amino acids with SOCl2-DMF leads to N-protected N-carboxy amino acid anhydrides, whereas treatment with cyanuric fluoride at low temperature gives mainly N,N-bis-protected amino acid fluorides, which are efficient ac
