The chemical compound "Si,Si'-difluoro-Si,Si,Si',Si'-tetramethyl-Si,Si'-butanediyl-bis-silane" is a complex organosilicon molecule with the formula C12H28F2Si4. It features a central butanediyl chain (-CH2CH2CH2CH2-) that connects two silicon atoms, each of which is bonded to two methyl groups (-CH3) and one fluorine atom (F). The structure can be visualized as two tetramethylsilane units linked by a butanediyl bridge, with each silicon atom also having a fluorine atom attached. Si,Si'-difluoro-Si,Si,Si',Si'-tetramethyl-Si,Si'-butanediyl-bis-silane is of interest in the field of organosilicon chemistry due to its unique structure and potential applications in materials science and as a precursor in the synthesis of more complex silicon-containing compounds.
The CAS Registry Mumber 590-82-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,9 and 0 respectively; the second part has 2 digits, 8 and 2 respectively. Calculate Digit Verification of CAS Registry Number 590-82: (5*5)+(4*9)+(3*0)+(2*8)+(1*2)=79 79 % 10 = 9 So 590-82-9 is a valid CAS Registry Number.
