"Z(OMe)-Glu(OBzl)-Met(O)-NHNH-Troc" represents a complex peptide sequence with specific chemical modifications. The "Z" group is a protecting group for the N-terminal amino group, often used in peptide synthesis to prevent unwanted side reactions. "OMe" stands for methoxy, which is part of the Z group. "Glu(OBzl)" indicates that the side chain of the glutamic acid residue is protected with a benzyl ester group, which is crucial for preventing side reactions during peptide synthesis. "Met(O)" signifies that the methionine residue has an oxidized sulfur atom, which can affect the peptide's reactivity and stability. "NHNH" represents a hydrazide group, which is used to cap the C-terminus of the peptide, and "Troc" is a protecting group for the terminal amine group, the 2,2,2-trichloroethoxycarbonyl group, which is used to prevent unwanted reactions at the peptide's C-terminus. This sequence is a synthetic peptide with strategic chemical modifications that are essential for its stability, solubility, and reactivity in various biological and chemical applications.
The CAS Registry Mumber 95878-49-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,5,8,7 and 8 respectively; the second part has 2 digits, 4 and 9 respectively. Calculate Digit Verification of CAS Registry Number 95878-49: (7*9)+(6*5)+(5*8)+(4*7)+(3*8)+(2*4)+(1*9)=202 202 % 10 = 2 So 95878-49-2 is a valid CAS Registry Number.
