"Z(OMe)-Leu-Arg(Mts)-NHNH-Troc" is a complex peptide sequence consisting of four amino acids: Z(OMe), Leu, Arg(Mts), and NHNH, with a Trocmethyl protecting group. Z(OMe) represents a benzyloxycarbonyl (Z) group with a methoxyethyl (OMe) substitution, which is commonly used in peptide synthesis to protect the N-terminal amino group. Leu, or leucine, is a hydrophobic amino acid. Arg(Mts) denotes an arginine residue with a 4-methyltrityl (Mts) protecting group on its side chain, which is used to protect the guanidinium group during peptide synthesis. NHNH signifies a terminal amino group, indicating the end of the peptide sequence. Trocmethyl, or troc, is a protecting group for the N-terminal amino group, which can be removed under specific conditions to reveal the free amine. This peptide sequence is likely used in the synthesis of larger peptides or proteins, with the protecting groups ensuring the correct sequence and preventing unwanted side reactions during the assembly process.
The CAS Registry Mumber 96105-40-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,6,1,0 and 5 respectively; the second part has 2 digits, 4 and 0 respectively. Calculate Digit Verification of CAS Registry Number 96105-40: (7*9)+(6*6)+(5*1)+(4*0)+(3*5)+(2*4)+(1*0)=127 127 % 10 = 7 So 96105-40-7 is a valid CAS Registry Number.
