20330-90-9 Usage
General Description
DIMETHYL 5-CHLOROISOPHTHALATE is a chemical compound that belongs to the esters class of chemicals. It is a colorless to yellow liquid that is often used as an intermediate in the production of various other chemicals. It is known to be a potential skin irritant and can cause eye irritation as well. This chemical is primarily used in the manufacturing of pharmaceuticals and agrochemicals and can also be used as a solvent. It is important to handle this chemical with care and follow proper safety protocols when working with it.
Check Digit Verification of cas no
The CAS Registry Mumber 20330-90-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,3,3 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20330-90:
(7*2)+(6*0)+(5*3)+(4*3)+(3*0)+(2*9)+(1*0)=59
59 % 10 = 9
So 20330-90-9 is a valid CAS Registry Number.

An alternative to the Sandmeyer approach to aryl iodides
Hu, Bao,Miller, William H.,Neumann, Kiel D.,Linstad, Ethan J.,DiMagno, Stephen G.
, p. 6394 - 6398 (2015/04/22)
Iodoarenes are important synthons for a wide range of organic transformations. Here we report a general strategy to prepare singly iodinated electron-rich aromatic compounds through the intermediacy of diaryliodonium salts. This process, which incorporates a phase separation that greatly simplifies product purification, is an attractive replacement for the Sandmeyer approach to iodoarenes that are otherwise difficult to access.
