Heptamethylbenzenonium cation, also known as 1,2,3,4,5,6,7-heptamethylbenzenonium, is a positively charged organic compound with the chemical formula C14H19+. It is derived from heptamethylbenzene, where one hydrogen atom is replaced by a positively charged hydrogen ion (H+), resulting in the formation of a cation. heptamethylbenzenonium cation is characterized by its highly symmetrical structure, with seven methyl groups (CH3) attached to the benzene ring. Heptamethylbenzenonium cation is an interesting subject in organic chemistry due to its unique properties and potential applications in various chemical reactions and processes.

5285-33-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5285-33-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,8 and 5 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5285-33:
(6*5)+(5*2)+(4*8)+(3*5)+(2*3)+(1*3)=96
96 % 10 = 6
So 5285-33-6 is a valid CAS Registry Number.
