"Z(OMe)-Ile-NHNH-Troc" is a complex chemical compound, which can be broken down into its constituent parts for better understanding. "Z" stands for the benzyloxycarbonyl group, a protecting group used in peptide synthesis. "OMe" represents the methoxy group, an alkyl group derived from methanol. "Ile" is the abbreviation for isoleucine, an essential amino acid. "NHNH" signifies a hydrazine group, which is a bidentate ligand often used in coordination chemistry. "Troc" is short for the 2,2,2-trichloroethoxycarbonyl group, another protecting group used in peptide synthesis. In summary, "Z(OMe)-Ile-NHNH-Troc" is a peptide derivative featuring a protected isoleucine residue with a benzyloxycarbonyl group, a methoxy group, a hydrazine group, and a trichloroethoxycarbonyl group, which is likely used in the synthesis of complex peptides or as a building block in organic chemistry.
The CAS Registry Mumber 83550-64-5 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, 6 and 4 respectively. Calculate Digit Verification of CAS Registry Number 83550-64: (7*8)+(6*3)+(5*5)+(4*5)+(3*0)+(2*6)+(1*4)=135 135 % 10 = 5 So 83550-64-5 is a valid CAS Registry Number.
