N-(1,2-diphenylethylidene)-4-methoxyaniline is a synthetic organic compound characterized by its unique molecular structure. It features a central aniline group, which is an aromatic amine, with a 4-methoxy substituent that introduces an electron-donating methoxy group. The ethylidene bridge connects two phenyl rings, creating a rigid structure that influences the compound's physical and chemical properties. N-(1,2-diphenylethylidene)-4-methoxyaniline is often used in the synthesis of dyes and pigments due to its ability to absorb light and reflect specific wavelengths, resulting in color. Its chemical structure also makes it a potential candidate for applications in materials science, such as in the development of organic light-emitting diodes (OLEDs) or other optoelectronic devices, where its electronic properties can be harnessed for light emission or charge transport.

1749-18-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1749-18-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,4 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1749-18:
(6*1)+(5*7)+(4*4)+(3*9)+(2*1)+(1*8)=94
94 % 10 = 4
So 1749-18-4 is a valid CAS Registry Number.
