Benzenamine, N-ethynyl-N-phenyl-, also known as N-phenyl-N-ethynylbenzenamine or 1-phenylethynylbenzenamine, is an organic compound with the chemical formula C14H11N. It is a derivative of aniline, where one hydrogen atom is replaced by an ethynyl group (-C≡CH) and another by a phenyl group (C6H5). This molecule is characterized by its linear structure, with the triple bond in the ethynyl group and the aromatic rings of the phenyl groups. It is an important intermediate in the synthesis of various organic compounds, particularly in the production of pharmaceuticals and dyes. The compound is known for its reactivity, especially in electrophilic aromatic substitution reactions, and is often used in the formation of more complex molecular structures.

4231-39-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4231-39-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,3 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4231-39:
(6*4)+(5*2)+(4*3)+(3*1)+(2*3)+(1*9)=64
64 % 10 = 4
So 4231-39-4 is a valid CAS Registry Number.
