(Ethoxy-dimethyl-silylmethyl)-phenyl-phosphinsaeure-ethylester, also known as ethyl (ethoxydimethylsilylmethyl)phenylphosphinate, is a complex organophosphorus compound with the chemical formula C12H23O3PSi. (Ethoxy-dimethyl-silylmethyl)-phenyl-phosphinsaeure-ethylester features a phosphorus atom bonded to an ethyl group, a phenyl group, and an ethoxydimethylsilylmethyl group. The ethoxydimethylsilylmethyl group consists of a silicon atom bonded to three methyl groups and an ethoxy group. (Ethoxy-dimethyl-silylmethyl)-phenyl-phosphinsaeure-ethylester is of interest in the field of organophosphorus chemistry, potentially for its applications in materials science, pharmaceuticals, or as a precursor in the synthesis of more complex molecules. It is important to note that handling and disposal of such compounds should be done with care due to their potential reactivity and toxicity.
The CAS Registry Mumber 839-43-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,3 and 9 respectively; the second part has 2 digits, 4 and 3 respectively. Calculate Digit Verification of CAS Registry Number 839-43: (5*8)+(4*3)+(3*9)+(2*4)+(1*3)=90 90 % 10 = 0 So 839-43-0 is a valid CAS Registry Number.
