Phenylethynyl trimethylsilane, also known as 1-(trimethylsilyl)-4-ethynylbenzene, is an organosilicon compound characterized by a phenyl group (C6H5) connected to an ethynyl group (C≡CH) through a silicon atom. The silicon atom is bonded to three methyl groups (CH3), making it a trimethylsilane derivative. This chemical is often used as a protecting group in organic synthesis, particularly for the ethynyl group, due to its stability and ease of removal under mild conditions. It is also employed in the synthesis of various organic compounds, such as pharmaceuticals and specialty chemicals, where the controlled addition of functional groups is required. The compound is known for its ability to participate in cross-coupling reactions, making it a valuable intermediate in the formation of carbon-carbon bonds.

Check Digit Verification of cas no

The CAS Registry Mumber 217-06-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,1 and 7 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 217-06:
(5*2)+(4*1)+(3*7)+(2*0)+(1*6)=41
41 % 10 = 1
So 217-06-1 is a valid CAS Registry Number.
