N-Methyl-carbaminsaeure-<3-pentachlorethyl-phenylester>, also known as N-methylcarbamoyl chloride pentachlorophenyl ester, is a chemical compound with the molecular formula C8H3Cl5NO2. It is a derivative of N-methylcarbamic acid, where the hydroxyl group is replaced by a pentachlorophenyl ester group. N-Methyl-carbaminsaeure-<3-pentachlorethyl-phenylester> is characterized by its potential reactivity and toxicity, as it contains both a carbamoyl chloride group and a pentachlorophenyl moiety. The pentachlorophenyl group is known for its high reactivity and can form esters with various compounds, while the N-methylcarbamoyl chloride group is a reactive intermediate often used in the synthesis of pesticides and other agrochemicals. Due to its hazardous nature, handling and use of N-Methyl-carbaminsaeure-<3-pentachlorethyl-phenylester> require strict safety measures and are typically restricted to controlled laboratory environments or industrial settings with proper safety protocols.
The CAS Registry Mumber 729-57-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,2 and 9 respectively; the second part has 2 digits, 5 and 7 respectively. Calculate Digit Verification of CAS Registry Number 729-57: (5*7)+(4*2)+(3*9)+(2*5)+(1*7)=87 87 % 10 = 7 So 729-57-7 is a valid CAS Registry Number.
