19026-91-6 Usage
Explanation
Different sources of media describe the Explanation of 19026-91-6 differently. You can refer to the following data:
1. The molecular formula represents the number of atoms of each element present in a molecule. In this case, the compound has 11 carbon (C) atoms, 8 hydrogen (H) atoms, and 2 fluorine (F) atoms.
2. The compound has a bicyclic structure, which means it consists of two fused rings. The first ring has 4 carbon atoms, and the second ring has 5 carbon atoms. The numbering of the carbon atoms starts from the bridgehead carbon (the one connecting the two rings) and proceeds in a clockwise direction. The two fluorine atoms are attached to the 11th carbon atom in the structure.
3. The presence of fluorine atoms and the strained bicyclic ring system in the compound make it highly reactive. Fluorine is the most electronegative element, and its presence can significantly influence the reactivity of the molecule.
4. The compound has a high degree of ring strain because of the fusion of two rings with different sizes (4 and 5 carbon atoms). This strain makes the molecule less stable and more prone to undergo reactions.
5. Due to its reactivity and unique structure, 11,11-difluorobicyclo[4.4.1]undeca-1,3,5,7,9-pentaene can be used as a building block or intermediate in the synthesis of complex organic molecules and pharmaceuticals.
6. The highly strained and reactive nature of the compound makes it an interesting subject for researchers studying new chemical reactions and reactivity patterns. Understanding these patterns can lead to the development of new synthetic methods and applications in organic chemistry.
7. The compound's unique structure and reactivity make it a valuable compound for study in the field of organic chemistry, which focuses on the study of carbon-containing compounds and their reactions.

Check Digit Verification of cas no
The CAS Registry Mumber 19026-91-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,0,2 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 19026-91:
(7*1)+(6*9)+(5*0)+(4*2)+(3*6)+(2*9)+(1*1)=106
106 % 10 = 6
So 19026-91-6 is a valid CAS Registry Number.
