Hexaphenyldigermane, also known as phenylgermane, is an organogermanium compound with the chemical formula (C6H5)3GeGe(C6H5)3. It is a colorless, crystalline solid that is insoluble in water but soluble in organic solvents. Hexaphenyldigermane is formed by the reaction of phenylmagnesium bromide with germanium tetrachloride. Hexaphenyldigermane is an important precursor in the synthesis of various organogermanium compounds and has potential applications in the fields of polymer chemistry, materials science, and pharmaceuticals. Due to its stability and unique properties, it has been extensively studied for its electronic, optical, and thermal characteristics.
The CAS Registry Mumber 2616-39-9 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 6 respectively; the second part has 2 digits, 3 and 9 respectively. Calculate Digit Verification of CAS Registry Number 2616-39: (6*2)+(5*6)+(4*1)+(3*6)+(2*3)+(1*9)=79 79 % 10 = 9 So 2616-39-9 is a valid CAS Registry Number.
