Benzyloxycarbonyl-L-alanyl-L-leucin-hydrazid, also known as Z-Ala-Leu-Hyd, is a peptide derivative that consists of three components: a benzyloxycarbonyl (Z) group, an L-alanine (Ala) residue, and an L-leucine (Leu) residue, with a hydrazide (Hyd) group at the end. Benzyloxycarbonyl-L-alanyl-L-leucin-hydrazid is often used in organic synthesis and peptide chemistry, particularly as a building block for the synthesis of larger peptides and proteins. The Z group serves as a protecting group for the carboxyl group, preventing unwanted side reactions during peptide synthesis, while the hydrazide group can be used for further functionalization or conjugation to other molecules. Z-Ala-Leu-Hyd is a valuable tool in the development of new pharmaceuticals, as it can be incorporated into peptide drugs or used to study peptide-protein interactions.
The CAS Registry Mumber 6697-75-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,9 and 7 respectively; the second part has 2 digits, 7 and 5 respectively. Calculate Digit Verification of CAS Registry Number 6697-75: (6*6)+(5*6)+(4*9)+(3*7)+(2*7)+(1*5)=142 142 % 10 = 2 So 6697-75-2 is a valid CAS Registry Number.
