Arsensaeure-tribenzylester, also known as tribenzyl arsonate or tribenzyl arsonic acid, is an organoarsenic compound with the chemical formula C18H15AsO3. It is a colorless, crystalline solid that is soluble in organic solvents and has a molecular weight of 346.2 g/mol. Arsensaeure-tribenzylester is formed by the esterification of benzyl alcohol with arsenic acid, resulting in a molecule that contains three benzyl groups attached to an arsenic atom. Arsensaeure-tribenzylester has been used in various applications, such as a chemical intermediate in the synthesis of pharmaceuticals and agrochemicals, as well as a precursor for the production of other organoarsenic compounds. However, due to its potential toxicity and environmental concerns, its use has been restricted in many countries.
The CAS Registry Mumber 5954-44-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,5 and 4 respectively; the second part has 2 digits, 4 and 4 respectively. Calculate Digit Verification of CAS Registry Number 5954-44: (6*5)+(5*9)+(4*5)+(3*4)+(2*4)+(1*4)=119 119 % 10 = 9 So 5954-44-9 is a valid CAS Registry Number.
