2-(buta-1,3-diynyl)biphenyl, also known as 2-ethynylbiphenyl or 2-phenylethynylbenzene, is an organic compound with the chemical formula C14H10. It is a colorless to pale yellow crystalline solid that is insoluble in water but soluble in organic solvents. 2-(buta-1,3-diynyl)biphenyl is characterized by its unique structure, featuring a biphenyl core with a buta-1,3-diynyl group attached to the 2-position of the biphenyl. The buta-1,3-diynyl group consists of two acetylene groups (C≡CH) connected by a single carbon atom, which contributes to the compound's reactivity and potential applications in various chemical reactions and synthesis processes. 2-(buta-1,3-diynyl)biphenyl is used as a building block in the synthesis of more complex organic molecules, particularly in the production of certain pharmaceuticals, agrochemicals, and advanced materials.

Check Digit Verification of cas no

The CAS Registry Mumber 7642-29-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,4 and 2 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7642-29:
(6*7)+(5*6)+(4*4)+(3*2)+(2*2)+(1*9)=107
107 % 10 = 7
So 7642-29-7 is a valid CAS Registry Number.
