Silane, chlorodifluoromethyl-, also known as chlorodifluoromethylsilane or (chlorodifluoromethyl)silane, is a chemical compound with the formula ClF2SiH3. It is a colorless, volatile, and highly reactive liquid that is used as a precursor in the production of various organosilicon compounds and as a silylating agent in organic synthesis. The compound is synthesized by reacting silicon tetrachloride with difluoromethyllithium or by reacting difluoromethylsilane with hydrochloric acid. Due to its reactivity, it is typically stored and handled under an inert atmosphere to prevent unwanted side reactions. Chlorodifluoromethylsilane is also used in the semiconductor industry for the deposition of silicon dioxide films and as a component in the production of specialty polymers and silicones.
The CAS Registry Mumber 420-59-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 0 respectively; the second part has 2 digits, 5 and 9 respectively. Calculate Digit Verification of CAS Registry Number 420-59: (5*4)+(4*2)+(3*0)+(2*5)+(1*9)=47 47 % 10 = 7 So 420-59-7 is a valid CAS Registry Number.
