"Z(OMe)-Ser-Leu-Arg(Mts)-Arg(Mts)-NHNH2" is a peptide compound consisting of five amino acids: Z(OMe)-Ser, Leu, Arg(Mts), Arg(Mts), and NHNH2. The "Z(OMe)" group is a protecting group for the N-terminus, while "Mts" is a protecting group for the guanidinium group of the arginine residues. This specific sequence and the presence of protecting groups suggest that the peptide is designed for a particular purpose, such as a pharmaceutical or research application, where the protection of certain functional groups is necessary to maintain the peptide's stability or to control its reactivity. The peptide's structure and the use of these protecting groups indicate a level of sophistication in its synthesis, likely intended for a specific biological target or to study peptide-protein interactions in a controlled manner.
The CAS Registry Mumber 99236-58-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,2,3 and 6 respectively; the second part has 2 digits, 5 and 8 respectively. Calculate Digit Verification of CAS Registry Number 99236-58: (7*9)+(6*9)+(5*2)+(4*3)+(3*6)+(2*5)+(1*8)=175 175 % 10 = 5 So 99236-58-5 is a valid CAS Registry Number.
