Trimethyl(pentamethylphenyl)silane is an organosilicon compound with the chemical formula C11H19Si. It is a colorless liquid that is soluble in organic solvents and has a molecular weight of 181.36 g/mol. Trimethyl(pentamethylphenyl)silan is characterized by a silicon atom bonded to three methyl groups and a pentamethylphenyl group, which consists of a benzene ring with five methyl substituents. Trimethyl(pentamethylphenyl)silane is used as a reagent in organic synthesis, particularly in the formation of carbon-silicon bonds, and as a protecting group in the synthesis of complex organic molecules. It is also employed as a ligand in transition metal-catalyzed reactions due to its ability to stabilize certain metal complexes. The compound is sensitive to air and moisture, and therefore, it is typically handled under an inert atmosphere.

Check Digit Verification of cas no

The CAS Registry Mumber 71236-49-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,2,3 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 71236-49:
(7*7)+(6*1)+(5*2)+(4*3)+(3*6)+(2*4)+(1*9)=112
112 % 10 = 2
So 71236-49-2 is a valid CAS Registry Number.
