1,3,9,11-Cyclotridecatetraene-5,7-diyne is a polycyclic aromatic hydrocarbon with a unique structure consisting of a 13-membered ring with alternating double and single bonds. It features two acetylenic groups at the 5 and 7 positions, which contribute to its reactivity and potential applications in organic synthesis. On the other hand, 4,9-bis(1,1-dimethylethyl)-13-[(2,3,4,5-tetraphenyl-2,4-cyclopentadien-1-ylidene)ethenylidene] is a complex, multi-ringed molecule with a cyclopentadienyl group and a phenyl-substituted ethynyl group. 1,3,9,11-Cyclotridecatetraene-5,7-diyne, 4,9-bis(1,1-dimethylethyl)-13-[(2,3,4,5-tetraphenyl-2,4-cyclopentadien-1 -ylidene)ethenylidene]- is characterized by its large, conjugated π-system and the presence of bulky tert-butyl groups, which may influence its electronic properties and potential use in materials science or as a precursor in the synthesis of other complex organic molecules. Both chemicals showcase the diversity and complexity of organic chemistry, with potential applications in various fields due to their unique structures and properties.

87399-13-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 87399-13-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,3,9 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 87399-13:
(7*8)+(6*7)+(5*3)+(4*9)+(3*9)+(2*1)+(1*3)=181
181 % 10 = 1
So 87399-13-1 is a valid CAS Registry Number.
