1,3,5-trichloro-2-methyl-benzene is a chemical compound with the molecular formula C7H5Cl3. It is a colorless liquid with a strong, sweet odor. It is primarily used as an intermediate in the chemical manufacturing industry, particularly in the production of pesticides, pharmaceuticals, and other organic chemicals. The compound is toxic and may be harmful if inhaled, ingested, or absorbed through the skin. It can cause irritation to the respiratory system, skin, and eyes, and may have detrimental effects on the liver and kidneys with prolonged or repeated exposure. 1,3,5-trichloro-2-methyl-benzene should be handled and stored with caution, and appropriate personal protective equipment should be used when working with this compound.
Check Digit Verification of cas no
The CAS Registry Mumber 23749-65-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,7,4 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 23749-65:
(7*2)+(6*3)+(5*7)+(4*4)+(3*9)+(2*6)+(1*5)=127
127 % 10 = 7
So 23749-65-7 is a valid CAS Registry Number.

Trichloroisocyanuric acid in 98% sulfuric acid: A superelectrophilic medium for chlorination of deactivated arenes
Mendo?a, Gabriela Fonseca,Senra, M?nica Rufino,Esteves, Pierre M.,De Mattos, Marcio C.S.
experimental part, p. 176 - 181 (2012/04/04)
Trichloroisocyanuric acid (TCCA) reacts with arenes and its reactivity is highly affected by the acid strength of the reaction medium. Deactivated arenes are efficiently chlorinated by TCCA in H2SO4. Our results, along with DFT calculations and 13C NMR spectrometry suggest the formation of a monoprotonated TCCA superelectrophile as the reactive species that can efficiently transfer electrophilic Cl+ to even very weak nucleophiles, such as m-dinitrobenzene.
