The chemical "Z-L-Val-Gly-L-Lys(BOC)-L-Lys(BOC)-L-Arg(NO2)-L-Arg(NO2)-L-Pro-OH" is a peptide compound consisting of a sequence of amino acids. It features a Z-group protecting the N-terminus, which is crucial for preventing unwanted side reactions during peptide synthesis. The sequence includes L-valine (L-Val), glycine (Gly), two L-lysine residues with BOC protecting groups (L-Lys(BOC)), and two L-arginine residues with nitro groups (L-Arg(NO2)). The presence of the BOC protecting groups on lysine indicates that this peptide is designed for stepwise synthesis, where the BOC group is removed in a controlled manner to allow for the addition of the next amino acid. The nitro groups on arginine are likely used for specific chemical reactivity or as a handle for further modification. The sequence ends with L-proline (L-Pro), which due to its cyclic structure, can introduce constraints in the peptide's conformation. This peptide is likely used in research or pharmaceutical development, possibly for studying protein-protein interactions or as a component of a drug candidate.

7669-63-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7669-63-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,6 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 7669-63:
(6*7)+(5*6)+(4*6)+(3*9)+(2*6)+(1*3)=138
138 % 10 = 8
So 7669-63-8 is a valid CAS Registry Number.

USE OF PENTAFLUOROPHENYL ESTERS IN THE SYNTHESIS OF INTERMEDIATE FRAGMENTS OF ACTH

Karel'skii, V. N.,Krysin, E. P.,Antonov, A. A.,Rostovskaya, G. E.

, p. 90 - 94 (2007/10/02)

The results are given of the synthesis of the heptapeptide 13-19 of the natural sequence of ACTH using, in a number of stages, the pentafluorophenyl esters of amino acids and peptides in combination with the temporary silyl protection of the carboxy group
