"Z(OMe)-Glu(OBzl)-Val-Leu-Glu(OBzl)-Met(O)-NHNH-Troc" represents a peptide sequence with specific chemical modifications. The peptide consists of six amino acids: Glutamic acid (Glu), Valine (Val), Leucine (Leu), Methionine (Met), and two additional Glutamic acid residues. The "Z(OMe)" prefix indicates that the N-terminal Glutamic acid is protected with a carbobenzoxy (Cbz) group, which is a common protecting group in peptide synthesis to prevent unwanted side reactions. The "OBzl" suffix on the second and fourth Glutamic acid residues signifies that these amino acids are also protected with benzyl ester groups. The "Met(O)" denotes that the Methionine residue has an oxidized sulfur atom, forming a methionine sulfoxide. The "NHNH-Troc" at the C-terminus suggests the presence of a Troc (2,2,2-trichloroethoxycarbonyl) group, which is used as a protecting group for the peptide's amine group, preventing it from participating in unwanted reactions. This specific sequence and its modifications are likely designed for a particular biological or chemical application, such as a drug candidate or a research tool in peptide chemistry.
The CAS Registry Mumber 95908-28-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,5,9,0 and 8 respectively; the second part has 2 digits, 2 and 8 respectively. Calculate Digit Verification of CAS Registry Number 95908-28: (7*9)+(6*5)+(5*9)+(4*0)+(3*8)+(2*2)+(1*8)=174 174 % 10 = 4 So 95908-28-4 is a valid CAS Registry Number.
