Z-Gly-Cys(Bz)-OMe is a synthetic peptide compound consisting of three amino acids: glycine (Gly), cysteine (Cys) with a benzyl (Bz) protecting group, and a methoxy (OMe) group. The "Z" prefix indicates the presence of a carbobenzoxy (Cbz) protecting group on the N-terminus, which is crucial for protecting the amino group during peptide synthesis. Z-Gly-Cys(Bz)-OMe is commonly used in the field of organic chemistry and peptide synthesis, as it allows for the controlled formation of peptide bonds and the subsequent removal of protecting groups to yield the desired peptide sequence. The benzyl group on the cysteine residue serves to protect the thiol group, preventing unwanted side reactions, while the methoxy group is typically used to improve solubility and stability of the compound in organic solvents.
The CAS Registry Mumber 5673-92-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,7 and 3 respectively; the second part has 2 digits, 9 and 2 respectively. Calculate Digit Verification of CAS Registry Number 5673-92: (6*5)+(5*6)+(4*7)+(3*3)+(2*9)+(1*2)=117 117 % 10 = 7 So 5673-92-7 is a valid CAS Registry Number.
