1-(Trimethylsilyl)-1,3-hexadiin is an organosilicon compound with the molecular formula C9H18Si. It is a colorless liquid that is soluble in organic solvents. 1-(Trimethylsilyl)-1,3-hexadiin is characterized by the presence of a trimethylsilyl group (SiMe3) attached to a 1,3-hexadiyne backbone, which consists of a six-carbon chain with a triple bond between the first and third carbon atoms. 1-(Trimethylsilyl)-1,3-hexadiin is synthesized by the reaction of 1,3-hexadiyne with trimethylsilyl chloride (TMSCl) in the presence of a base, such as triethylamine. It is used as a reagent in organic synthesis, particularly in the protection of alkynes and the formation of silyl enol ethers. Due to its reactivity, it should be handled with care, and safety precautions should be taken during its use and storage.

2750-69-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2750-69-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,5 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2750-69:
(6*2)+(5*7)+(4*5)+(3*0)+(2*6)+(1*9)=88
88 % 10 = 8
So 2750-69-8 is a valid CAS Registry Number.
