"Z-Arg(NO2)-Gly-Phe-Phe-OMe" is a synthetic peptide consisting of five amino acids: Z-Arg(NO2), Gly, Phe, Phe, and OMe. The "Z" group is a protecting group used in peptide synthesis to prevent unwanted side reactions. Arg(NO2) represents an arginine residue with a nitro group (NO2) attached, which can influence the peptide's properties. Gly is glycine, the simplest amino acid. Phe stands for phenylalanine, an aromatic amino acid, and it appears twice in this sequence, indicating a repetition that may be significant for the peptide's structure or function. OMe is a methoxy group, which is often used as a protecting group or to modify the peptide's properties. This specific sequence and the modifications may be designed for particular biological activities or as a research tool in peptide chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 99260-30-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,2,6 and 0 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 99260-30:
(7*9)+(6*9)+(5*2)+(4*6)+(3*0)+(2*3)+(1*0)=157
157 % 10 = 7
So 99260-30-7 is a valid CAS Registry Number.

Cleavage of Z-Group and Formation of Hydantoine during Saponification of Z-Peptide Esters

Schwenzer, B.,Weber, E.,Losse, G.

, p. 479 - 486 (2007/10/02)

In the course of alkaline decomposition of the tetrapeptide ester Z-Arg(NO2)-Gly-Phe-Phe-OMe one gets a high output of a by-product.The latter was isolated and identified by 13C-n.m.r. spectroscopy to be the hydantoine derivative arising from a loss of Z-
