Boc-Val-Orn(Z)-Leu-D-Phe-Pro-OEt is a peptide compound consisting of seven amino acids: Boc-protected valine (Val), ornithine with a Z group (Orn(Z)), leucine (Leu), D-phenylalanine (D-Phe), and proline (Pro), with an ethyl ester (OEt) at the C-terminus. This sequence is designed to have specific biological activity, potentially serving as a precursor for pharmaceuticals or as a research tool in studying peptide interactions. The Boc group is a protecting group for the amino group, which is crucial during synthesis to prevent unwanted side reactions. The Z group is a protecting group for the side chain of ornithine, ensuring that the peptide chain is formed correctly. The D-configuration of phenylalanine indicates that it is the non-natural isomer of the amino acid, which can be important for the peptide's function or stability. This specific sequence and its protective groups make it a complex and potentially valuable molecule in the field of peptide chemistry and drug development.

Check Digit Verification of cas no

The CAS Registry Mumber 5519-68-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,1 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5519-68:
(6*5)+(5*5)+(4*1)+(3*9)+(2*6)+(1*8)=106
106 % 10 = 6
So 5519-68-6 is a valid CAS Registry Number.

ONE-POT CYCLIZATION OF A PEPTIDE BY THE USE OF (5-NITROPYRIDYL)DIPHENYL PHOSPHINATE: THE SYNTHESIS OF CYCLIC DECAPEPTIDE GRAMICIDIN S

Mukaiyama, Teruaki,Kamekawa, Kenichi,Watanabe, Yutaka

, p. 1367 - 1370 (2007/10/02)

One-pot synthesis of gramicidin S, cyclic decapeptide, was successfully achieved by treatment of the corresponding linear decapeptide with (5-nitropyridyl)diphenyl phosphinate, a new condensing reagent, in pyridine.Similarly, the phosphinic ester can be successfully employed in the Young test as well as syntheses of dipeptides.
