"Z(OMe)-Lys(Z)-Lys(Z)-Tyr-OMe" is a peptide compound consisting of five amino acid residues: Z(OMe), Lys(Z), Lys(Z), Tyr, and OMe. Z(OMe) represents a protected amino group, while Lys(Z) denotes lysine with a benzyloxycarbonyl (Z) protecting group. Tyr stands for tyrosine, and OMe signifies a methoxy group. This specific sequence of amino acids is designed to protect the peptide from degradation and ensure its stability during synthesis and purification processes. The presence of the Z group on lysine residues and the OMe group on the terminal amino acid contribute to the overall structure and reactivity of the peptide, making it a valuable compound for various applications in the fields of chemistry, biology, and pharmaceuticals.
The CAS Registry Mumber 89762-75-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,7,6 and 2 respectively; the second part has 2 digits, 7 and 5 respectively. Calculate Digit Verification of CAS Registry Number 89762-75: (7*8)+(6*9)+(5*7)+(4*6)+(3*2)+(2*7)+(1*5)=194 194 % 10 = 4 So 89762-75-4 is a valid CAS Registry Number.
