α-Acetyl-p-chlor-cis-zimtsaeuremethylester, also known as α-Acetyl-p-chloro-cis-cinnamaldehyde dimethyl acetal, is a chemical compound derived from cinnamaldehyde, a naturally occurring organic compound found in cinnamon. This specific compound features a chloro group at the para position, an acetyl group at the alpha position, and a cis-configuration, which refers to the geometric arrangement of the double bond in the molecule. It is used as a flavoring agent and fragrance component in various industries, such as food, beverages, and cosmetics, due to its unique aroma and taste. The compound is synthesized through a series of chemical reactions, and its properties, such as solubility and stability, are influenced by the presence of the chloro and acetyl groups.

Check Digit Verification of cas no

The CAS Registry Mumber 14678-84-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,6,7 and 8 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 14678-84:
(7*1)+(6*4)+(5*6)+(4*7)+(3*8)+(2*8)+(1*4)=133
133 % 10 = 3
So 14678-84-3 is a valid CAS Registry Number.

Cross-linked polystyrene-TiCl4 complex as a reusable Lewis acid catalyst for solvent-free Knoevenagel condensations of 1,3-dicarbonyl compounds with aldehydes

Rahmatpour, Ali,Goodarzi, Niloofar

, p. 24 - 31 (2019)

Cross-linked polystyrene copolymer beads with the average particle size in the range of (50–80 mesh size) were prepared by a new method, characterized and functionalized with titanium tetrachloride to afford the corresponding polystyrene?titanium tetrachloride complex in one step reaction and characterized by FT-IR, UV, TGA, DSC, XRD, SEM, BET. This polymer metal complex (PS/TiCl4) was used as a heterogeneous, recoverable, reusable Lewis acid for solvent-free Knoevenagel condensations of 1,3-diketones with aromatic aldehydes under green and mild conditions. The rate of reactions was found to decrease with an increasing percentage of crosslinking and the mesh size of the copolymer beads. This complex showed good stability and catalytic activity in the Knoevenagel reactions.
