1,8-bis(4-nitrophenyl)octa-1,3,5,7-tetrayne is a complex organic compound characterized by its unique structure and properties. This molecule consists of an octatetrayne backbone, which is a linear acetylenic compound with four carbon-carbon triple bonds, arranged in a 1,3,5,7-tetrayne pattern. The two terminal carbon atoms are connected to 4-nitrophenyl groups, which are phenyl rings substituted with nitro groups at the para position. 1,8-bis(4-nitrophenyl)octa-1,3,5,7-tetrayne is known for its rigid structure and potential applications in materials science, such as in the development of conjugated polymers and organic electronics. The presence of nitro groups also imparts specific chemical reactivity and stability characteristics to the molecule, making it a subject of interest in synthetic chemistry and material research.

7642-38-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7642-38-8 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, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7642-38:
(6*7)+(5*6)+(4*4)+(3*2)+(2*3)+(1*8)=108
108 % 10 = 8
So 7642-38-8 is a valid CAS Registry Number.
