  • or
2-(2,5-dichlorophenyl)-2-oxoacetic acid, also known as 2,5-dichlorophenoxyacetic acid or DCPA, is a synthetic chemical compound with the molecular formula C8H6Cl2O3. It is a white crystalline solid that is soluble in water and has a molecular weight of 221.03 g/mol. DCPA is primarily used as a pre-emergent herbicide to control the growth of various annual grasses and broadleaf weeds in agricultural fields, particularly in crops like corn, soybeans, and cotton. It works by inhibiting cell division in the meristematic tissues of plants, leading to their death. Due to its potential environmental and health risks, its use is regulated in many countries, and it is classified as a restricted-use pesticide in some regions.

Check Digit Verification of cas no

The CAS Registry Mumber 26767-05-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,7,6 and 7 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 26767-05:
(7*2)+(6*6)+(5*7)+(4*6)+(3*7)+(2*0)+(1*5)=135
135 % 10 = 5
So 26767-05-5 is a valid CAS Registry Number.

, p. 3640 - 3642 (2013)

CuBr2-catalyzed decarboxylative acylation of the acyl C-H of N-monosubstituted and N,N-disubstituted formamides with α-oxocarboxylic acids leading to α-ketoamides was developed, which generated the corresponding products in good yields. The Royal Society of Chemistry 2013.

Photoredox Catalysis Enables Decarboxylative Cyclization with Hypervalent Iodine(III) Reagents: Access to 2,5-Disubstituted 1,3,4-Oxadiazoles

Li, Jian,Lu, Xue-Chen,Xu, Yue,Wen, Jin-Xia,Hou, Guo-Quan,Liu, Li

supporting information, p. 9621 - 9626 (2020/12/21)

A novel approach to 2,5-disubstituted 1,3,4-oxadiazoles derivatives via a decarboxylative cyclization reaction by photoredox catalysis between commercially available α-oxocarboxylic acids and hypervalent iodine(III) reagent is described. This powerful transformation involves the coupling reaction between two different kinds of radical species and the formation of C-N and C-O bonds.
