Lithium, m-1,4-butanediyldi-, also known as dilithium m-xylenediide, is an inorganic compound with the chemical formula Li2(C6H4). It is a colorless, crystalline solid that is highly sensitive to moisture and air. Lithium, m-1,4-butanediyldi- is formed by the reaction of lithium metal with m-xylene, a derivative of xylene, which is an aromatic hydrocarbon. Dilithium m-xylenediide is an important intermediate in the synthesis of various organolithium compounds, which are widely used in organic synthesis, particularly in the formation of carbon-carbon bonds. Due to its reactivity, it is typically handled under an inert atmosphere or in a vacuum to prevent unwanted side reactions.

2123-72-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2123-72-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,2 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2123-72:
(6*2)+(5*1)+(4*2)+(3*3)+(2*7)+(1*2)=50
50 % 10 = 0
So 2123-72-0 is a valid CAS Registry Number.
