O-bis(trichlorosilyl)benzene, also known as 1,2-bis(trichlorosilyl)benzene, is an organosilicon compound with the chemical formula C6H4Cl6Si2. It is a colorless, crystalline solid that is insoluble in water but soluble in organic solvents. o-bis(trichlorosilyl)benzene is formed by the substitution of two hydrogen atoms on the benzene ring with trichlorosilyl groups (SiCl3), resulting in a symmetrical structure. O-bis(trichlorosilyl)benzene is primarily used as a precursor in the synthesis of various organosilicon polymers and materials, such as silicones and silane coupling agents. Due to its reactivity and potential toxicity, it is essential to handle o-bis(trichlorosilyl)benzene with care and proper safety measures.
The CAS Registry Mumber 6838-77-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,3 and 8 respectively; the second part has 2 digits, 7 and 7 respectively. Calculate Digit Verification of CAS Registry Number 6838-77: (6*6)+(5*8)+(4*3)+(3*8)+(2*7)+(1*7)=133 133 % 10 = 3 So 6838-77-3 is a valid CAS Registry Number.
