(Z)-2-penten-2-yl-lithium is an organolithium compound with the chemical formula C5H9Li. It is a colorless liquid that is highly reactive and sensitive to air and moisture. (Z)-2-penten-2-yl-lithium is an important reagent in organic synthesis, particularly in the formation of carbon-carbon bonds through the use of the lithium reagent. It is commonly used in the preparation of various organic compounds, such as alkenes, alkynes, and arenes, by reacting with electrophiles like carbonyl compounds, halides, and other organic substrates. Due to its high reactivity, it must be handled with extreme care under an inert atmosphere, typically using techniques such as Schlenk line or glovebox to prevent unwanted side reactions.
The CAS Registry Mumber 83269-80-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,2,6 and 9 respectively; the second part has 2 digits, 8 and 0 respectively. Calculate Digit Verification of CAS Registry Number 83269-80: (7*8)+(6*3)+(5*2)+(4*6)+(3*9)+(2*8)+(1*0)=151 151 % 10 = 1 So 83269-80-1 is a valid CAS Registry Number.
