Pentaethoxyarsorane, also known as arsenic pentaethoxide, is an organoarsenic compound with the chemical formula As(OC2H5)5. It is a colorless, volatile, and highly toxic liquid that is soluble in organic solvents. Pentaethoxyarsorane is formed by the reaction of arsenic trichloride with ethanol in the presence of a base, such as sodium ethoxide. Pentaethoxyarsorane is primarily used as a precursor in the synthesis of various organoarsenic compounds, which have applications in the fields of pharmaceuticals, agriculture, and materials science. Due to its high toxicity, handling and storage of pentaethoxyarsorane require strict safety precautions to minimize exposure and potential health risks.
The CAS Registry Mumber 5954-41-6 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 1 respectively. Calculate Digit Verification of CAS Registry Number 5954-41: (6*5)+(5*9)+(4*5)+(3*4)+(2*4)+(1*1)=116 116 % 10 = 6 So 5954-41-6 is a valid CAS Registry Number.
