"Z-(2RS,3RS)-AHPA(p-Cl)-Leu-OBzl" is a complex chemical compound with a unique structure. It is a peptide derivative, where "Z" represents the benzyloxycarbonyl (Cbz) protecting group, a common strategy in peptide synthesis to prevent unwanted side reactions. The compound consists of a central AHPA (2-amino-4-hydroxy-6-phenylhexanoic acid) unit, which is a non-proteinogenic amino acid, with a para-chloro (p-Cl) substitution on the phenyl ring. This is linked to a leucine (Leu) residue, which is a natural amino acid. The "OBzl" indicates that the hydroxyl group of the AHPA is benzylated, which is another protecting group used in organic synthesis. Z-(2RS,3RS)-AHPA(p-Cl)-Leu-OBzl is likely used in advanced chemical research, particularly in the field of peptide chemistry, where such protected amino acid derivatives are crucial for the synthesis of complex peptides and proteins with specific properties.
The CAS Registry Mumber 63219-65-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,2,1 and 9 respectively; the second part has 2 digits, 6 and 5 respectively. Calculate Digit Verification of CAS Registry Number 63219-65: (7*6)+(6*3)+(5*2)+(4*1)+(3*9)+(2*6)+(1*5)=118 118 % 10 = 8 So 63219-65-8 is a valid CAS Registry Number.
