Bis(triphenylsilyl)ketone is an organosilicon compound with the chemical formula (Ph3Si)2CO. It is a colorless, crystalline solid that is sensitive to air and moisture. bis(triphenylsilyl)ketone is formed by the reaction of triphenylsilyl chloride with lithium acetylide. Bis(triphenylsilyl)ketone is an important intermediate in the synthesis of various organosilicon compounds, such as silyl enol ethers and silyl ketene acetals. It is also used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds. Due to its sensitivity to air and moisture, it is typically handled under an inert atmosphere or in a glovebox.

Check Digit Verification of cas no

The CAS Registry Mumber 4916-43-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,1 and 6 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4916-43:
(6*4)+(5*9)+(4*1)+(3*6)+(2*4)+(1*3)=102
102 % 10 = 2
So 4916-43-2 is a valid CAS Registry Number.
