Bis(triethylsilyl)phenylarsonate is a chemical compound with the formula [PhAs(SiEt3)2], where Ph represents a phenyl group, As is arsenic, and SiEt3 denotes triethylsilyl groups. This organoarsenic compound is characterized by its two triethylsilyl groups attached to an arsenic atom, which is in turn bonded to a phenyl group. It is a colorless, viscous liquid that is sensitive to air and moisture. Bis(triethylsilyl)phenylarsonate is primarily used as a reagent in organic synthesis, particularly in the formation of aryl-arsenic bonds and as a precursor to other organoarsenic compounds. Due to its reactivity and potential toxicity, it is essential to handle bis(triethylsilyl)phenylarsonate with care, using appropriate safety measures and equipment.
The CAS Registry Mumber 2809-11-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,0 and 9 respectively; the second part has 2 digits, 1 and 1 respectively. Calculate Digit Verification of CAS Registry Number 2809-11: (6*2)+(5*8)+(4*0)+(3*9)+(2*1)+(1*1)=82 82 % 10 = 2 So 2809-11-2 is a valid CAS Registry Number.
