Bis--dimethyl-silan, also known as 1,1-dimethyl-N,N'-bis(phenylhydrazono)silan, is an organosilicon compound with the chemical formula C14H16N2Si. It is a colorless to pale yellow crystalline solid that is soluble in common organic solvents. Bis--dimethyl-silan is formed by the reaction of dimethyldichlorosilane with phenylhydrazine, resulting in a molecule that features two phenylhydrazone groups attached to a central silicon atom, which is also bonded to two methyl groups. It is used in the synthesis of various organosilicon compounds and as a reagent in organic chemistry. Due to its sensitivity to moisture and air, it is typically stored under an inert atmosphere and handled with care.
The CAS Registry Mumber 6026-18-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,0,2 and 6 respectively; the second part has 2 digits, 1 and 8 respectively. Calculate Digit Verification of CAS Registry Number 6026-18: (6*6)+(5*0)+(4*2)+(3*6)+(2*1)+(1*8)=72 72 % 10 = 2 So 6026-18-2 is a valid CAS Registry Number.
