2,4-bis(chloromethyl)toluene is a chemical compound with the molecular formula C9H10Cl2. It is also known as benzaldehyde, 2,4-dichloro-, acetal. The compound appears as a colorless to light yellow liquid with a strong, pungent odor. It is commonly used as an intermediate for the synthesis of various organic compounds, including pharmaceuticals, pesticides, and dyes. 2,4-bis(chloromethyl)toluene is also used in the production of epoxy resins, which are widely used in the manufacturing of adhesives, coatings, and composites. The chemical is considered hazardous and should be handled with caution due to its potential to cause skin and eye irritation, as well as respiratory and gastrointestinal discomfort.
Check Digit Verification of cas no
The CAS Registry Mumber 2735-05-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,3 and 5 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2735-05:
(6*2)+(5*7)+(4*3)+(3*5)+(2*0)+(1*5)=79
79 % 10 = 9
So 2735-05-9 is a valid CAS Registry Number.

An experimental and theoretical study on imidazolium-based ionic liquid promoted chloromethylation of aromatic hydrocarbons
Wang, Yun,Xi, Yanli
, p. 2196 - 2199 (2014/03/21)
The chloromethylation of aromatic hydrocarbons proceeded efficiently using the reusable imidazolium-based ionic liquid as promoter. Mild reaction conditions, enhanced rates, improved yields, recyclability of ionic liquids, and reagents' reactivity which is different from that in conventional organic solvents are the remarkable features observed in ionic liquids. The ionic liquids were recycled in three subsequent runs with no decrease in activity. In addition, the results of calculations with the Gaussian 98 suite of program are in good accordance with the experimental outcomes.
