5-(4-Fluor-benzyliden)-5H-dibenzo[a,d]cyclohepten is a complex organic compound with the molecular formula C20H13F. It is characterized by a dibenzo[a,d]cyclohepten core, which is a type of tricyclic aromatic system. The compound features a 4-fluorobenzyl group attached to the 5-position of the dibenzo[a,d]cyclohepten framework, which introduces a fluorine atom into the molecule. This fluorine substitution can significantly alter the compound's electronic properties and reactivity compared to its non-fluorinated analogs. The compound is of interest in medicinal chemistry and materials science due to its potential applications in the development of new drugs and advanced materials. Its synthesis and properties are subjects of ongoing research, with the aim of understanding its behavior in various chemical and biological contexts.

Check Digit Verification of cas no

The CAS Registry Mumber 1236-67-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,3 and 6 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1236-67:
(6*1)+(5*2)+(4*3)+(3*6)+(2*6)+(1*7)=65
65 % 10 = 5
So 1236-67-5 is a valid CAS Registry Number.

Reduction of benzylidene dibenzo[ a, d ]cycloheptenes: Over-reduction of antiaromatic dianions to aromatic tetraanions

Tresca, Blakely,Higbee, MacDonald,Mills, Nancy S.

experimental part, p. 5539 - 5546 (2011/08/21)

The antiaromaticity of a series of dianions of p-substituted benzylidene dibenzo[a,d]cycloheptenes was examined through calculated measures of antiaromaticity. The nucleus-independent chemical shifts (NICS) and magnetic susceptibility exaltation both show
