Dimesityl-methyl-silylazid, also known as 1,1,1,2-tetramethyl-2-(2,4,6-trimethylphenyl)disilane or (2,4,6-trimethylphenyl)dimethylsilylmethylazide, is an organosilicon compound with the chemical formula C11H19NSi2. It is a colorless liquid that is sensitive to air and moisture, and it is commonly used as a reagent in organic synthesis, particularly in the formation of carbon-nitrogen bonds. The compound is characterized by its two dimethylsilyl groups attached to a central silicon atom, with one of the silicon atoms also bonded to a methyl group and an azide group. Dimesityl-methyl-silylazid is known for its stability and reactivity, making it a valuable tool in the synthesis of various organic compounds.
The CAS Registry Mumber 5599-35-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,9 and 9 respectively; the second part has 2 digits, 3 and 5 respectively. Calculate Digit Verification of CAS Registry Number 5599-35: (6*5)+(5*5)+(4*9)+(3*9)+(2*3)+(1*5)=129 129 % 10 = 9 So 5599-35-9 is a valid CAS Registry Number.
