General Description
5-Chloro-2-iodotoluene is a chemical compound with the molecular formula C7H6CI. It is a halogenated aromatic compound that consists of a toluene molecule with chlorine and iodine substituents. 5-Chloro-2-iodotoluene is most commonly used as an intermediate in the synthesis of various organic compounds, particularly in the pharmaceutical and agrochemical industries. It is also used as a building block for the production of dyes, pigments, and other fine chemicals. 5-Chloro-2-iodotoluene is a versatile and important chemical reagent that plays a crucial role in the development of many valuable products.
Check Digit Verification of cas no
The CAS Registry Mumber 23399-70-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,3,9 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 23399-70:
(7*2)+(6*3)+(5*3)+(4*9)+(3*9)+(2*7)+(1*0)=124
124 % 10 = 4
So 23399-70-4 is a valid CAS Registry Number.

Regioselective iodination of chlorinated aromatic compounds using silver salts
Joshi, Sudhir N.,Vyas, Sandhya M.,Wu, Huimin,Duffel, Michael W.,Parkin, Sean,Lehmler, Hans-Joachim
experimental part, p. 7461 - 7469 (2011/10/10)
The iodination of chlorinated aromatic compounds using Ag 2SO4/I2, AgSbF6/I2, AgBF4/I2, and AgPF6/I2 offers access to iodoarenes that are valuable intermediates in organic synthesis. Specifically, iodination of phenols, anisoles, and anilines with a 3,5-dichloro substitution pattern preferentially yielded the ortho, para, and para iodinated product, respectively. In the case of chlorobenzene and 3-chlorotoluene, AgSbF6/I2, AgBF4/I2, and AgPF 6/I2, but not Ag2SO4/I2, selectively introduced the iodine in para position to the chlorine substituent.
