"Z(OMe)-Glu(OBzl)-Lys(Z)-Lys(Z)-Glu(OBzl)-Val-NHNH2" is a complex peptide sequence consisting of seven amino acids. It features a unique arrangement and protection scheme, which is crucial for its stability and reactivity. The peptide starts with Z(OMe)-protected glutamic acid (Glu), which is followed by benzyl-protected lysine (Lys), another Z-protected lysine, and another benzyl-protected glutamic acid. The sequence then includes a valine (Val) and ends with a terminal NHNH2 group, indicating a free amine group capable of forming a peptide bond. This specific sequence and protection pattern are designed to facilitate controlled peptide synthesis, where the Z and OBzl groups are temporary protecting groups that shield the amino and carboxylic acid groups, respectively, from unwanted side reactions during the synthesis process. The final product, once deprotected, would be a peptide with specific biological or chemical properties, depending on its intended application.
The CAS Registry Mumber 83550-56-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,5,5 and 0 respectively; the second part has 2 digits, 5 and 6 respectively. Calculate Digit Verification of CAS Registry Number 83550-56: (7*8)+(6*3)+(5*5)+(4*5)+(3*0)+(2*5)+(1*6)=135 135 % 10 = 5 So 83550-56-5 is a valid CAS Registry Number.
