The chemical compound "Si,Si,Si',Si'-tetraethoxy-Si,Si'-dimethyl-Si,Si'-p-phenylene-bis-silane" is a complex organosilicon compound with the molecular formula C16H28O4Si4. It features a p-phenylene (benzene) core with two silicon atoms attached to each of its carbon atoms. Each silicon atom is further bonded to two ethoxy groups (C2H5O) and one methyl group (CH3), resulting in a symmetrical structure. Si,Si,Si',Si'-tetraethoxy-Si,Si'-dimethyl-Si,Si'-p-phenylene-bis-silane is notable for its potential applications in materials science, particularly in the synthesis of silicone polymers and as a precursor in the production of various silicone-based materials due to its ability to bridge organic and inorganic components.
The CAS Registry Mumber 2615-20-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,1 and 5 respectively; the second part has 2 digits, 2 and 0 respectively. Calculate Digit Verification of CAS Registry Number 2615-20: (6*2)+(5*6)+(4*1)+(3*5)+(2*2)+(1*0)=65 65 % 10 = 5 So 2615-20-5 is a valid CAS Registry Number.
