General Description
2,4-Dichloro-6-fluorobenzaldehyde, also known as DCFA, is a chemical compound with the molecular formula C7H3Cl2FO. It is a white to off-white solid that is used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. DCFA is a derivative of benzaldehyde, containing both chlorine and fluorine substituents. It is also utilized in the production of dyes, pigments, and other fine chemicals. The compound is known for its strong and pungent odor and should be handled with caution due to its potential health hazards.
Check Digit Verification of cas no
The CAS Registry Mumber 681435-09-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,1,4,3 and 5 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 681435-09:
(8*6)+(7*8)+(6*1)+(5*4)+(4*3)+(3*5)+(2*0)+(1*9)=166
166 % 10 = 6
So 681435-09-6 is a valid CAS Registry Number.

Pd-Catalyzed, ortho C-H Methylation and Fluorination of Benzaldehydes Using Orthanilic Acids as Transient Directing Groups
Chen, Xiao-Yang,Sorensen, Erik J.
supporting information, p. 2789 - 2792 (2018/03/08)
The direct, Pd-catalyzed ortho C-H methylation and fluorination of benzaldehydes have been accomplished using commercially available orthanilic acids as transient directing groups. In these reactions, the 1-fluoro-2,4,6-trimethylpyridinium salts can be either a bystanding F+ oxidant or an electrophilic fluorinating reagent. An X-ray crystal structure of a benzaldehyde ortho C-H palladation intermediate was obtained using triphenylphosphine as the stabilizing ligand.
