Z-Leu-Gly-Cys(Bzl)-Gln-OH is a peptide compound consisting of five amino acids: Leucine (Leu), Glycine (Gly), Cysteine (Cys) with a benzyl (Bzl) protecting group, Glutamine (Gln), and a terminal hydroxyl group (OH). The "Z" group is a benzyloxycarbonyl (Cbz) protecting group, which is commonly used in peptide synthesis to protect the amino group of the first amino acid in the sequence. This peptide is of interest in the field of chemistry and biochemistry, particularly in the study of protein structure and function, as well as in the development of new drugs and therapeutics. The specific sequence and protecting groups in Z-Leu-Gly-Cys(Bzl)-Gln-OH make it a valuable tool for researchers studying peptide interactions and the effects of different amino acid sequences on protein folding and stability.
The CAS Registry Mumber 76314-77-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,3,1 and 4 respectively; the second part has 2 digits, 7 and 7 respectively. Calculate Digit Verification of CAS Registry Number 76314-77: (7*7)+(6*6)+(5*3)+(4*1)+(3*4)+(2*7)+(1*7)=137 137 % 10 = 7 So 76314-77-7 is a valid CAS Registry Number.
