"Z(OMe)-Gln-Lys(Z)-Gly-OMe" is a peptide compound consisting of four amino acids: glutamine (Gln), lysine (Lys), and glycine (Gly), with two protecting groups, Z(OMe) and Z, attached to the N-terminus and the side chain of lysine, respectively. The Z(OMe) group is a benzyloxycarbonyl (Cbz) protecting group with a methoxyethyl (OMe) substitution, while the Z group is another Cbz protecting group. This specific sequence and protection scheme are crucial for the synthesis and stability of the peptide, as the protecting groups prevent unwanted side reactions during the peptide synthesis process. The compound is often used in peptide synthesis and research, where the protecting groups are later removed to reveal the free amino acid side chains, allowing for further reactions or biological studies.
The CAS Registry Mumber 62074-50-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,0,7 and 4 respectively; the second part has 2 digits, 5 and 0 respectively. Calculate Digit Verification of CAS Registry Number 62074-50: (7*6)+(6*2)+(5*0)+(4*7)+(3*4)+(2*5)+(1*0)=104 104 % 10 = 4 So 62074-50-4 is a valid CAS Registry Number.
