Trimethylsilyl-diphenyl-acetophenon, also known as 1-(trimethylsilyl)-1,2-diphenylethanone, is an organic compound with the chemical formula C15H18OSi. It is a colorless to pale yellow liquid that is soluble in organic solvents. Trimethylsilyl-diphenyl-acetophenon is characterized by a trimethylsilyl group (SiMe3) attached to a diphenylacetone moiety, which consists of a ketone group (C=O) bonded to two phenyl rings. Trimethylsilyl-diphenyl-acetophenon is used as a reagent in organic synthesis, particularly in the protection of carbonyl groups and as a precursor in the synthesis of various pharmaceuticals and agrochemicals. It is also employed in the preparation of silyl enol ethers, which are important intermediates in organic chemistry. The compound is sensitive to moisture and air, and should be handled under an inert atmosphere.

Check Digit Verification of cas no

The CAS Registry Mumber 27674-89-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,6,7 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 27674-89:
(7*2)+(6*7)+(5*6)+(4*7)+(3*4)+(2*8)+(1*9)=151
151 % 10 = 1
So 27674-89-1 is a valid CAS Registry Number.
