13142-56-8 Usage
General Description
1-(2,5-Dichlorophenyl)-3-phenylurea is a chemical compound commonly known as diuron. It is an herbicide used to control the growth of weeds in agriculture and horticulture. Diuron works by inhibiting photosynthesis in plants, which ultimately leads to their death. It is often applied to the soil or sprayed directly onto crops to prevent weed growth. Diuron is persistent in the environment and has been found to have negative impacts on aquatic organisms, leading to its restriction and regulation in some regions. Studies have also suggested potential risks to human health with long-term exposure to diuron, making it important to handle and use this chemical with caution.
Check Digit Verification of cas no
The CAS Registry Mumber 13142-56-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,1,4 and 2 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 13142-56:
(7*1)+(6*3)+(5*1)+(4*4)+(3*2)+(2*5)+(1*6)=68
68 % 10 = 8
So 13142-56-8 is a valid CAS Registry Number.

Synthesis and structure activity relationships in diphenylureas against Culex quinouefasciatus
Minatchy, S.,Mathew, Nisha
, p. 1066 - 1068 (2007/10/03)
Substituted diphenylureas 1-23 have been synthesised from isocyanates generated from azides of benzoic acid and 4-chlorobenzoic acid with aniline, and 4-chloro-, 2-trifluoromethyl-, 3-trifluoromethyl, 4-phenoxy-, 2,4-dichloro-, 2,5-dichloro-, 3,4-dichloro-, 3-chloro-4-methoxy-, 3-chloro-2-methyl-, 3-chloro-4-methyl- and 4-nitro-anilines. All the compounds have been tested for insect growth regulating (IGR) activity against early third instar larvae of Culex quinquefasciatus, the human filariasis vector. Compounds 15 and 19 exhibit 100 percent emergence inhibition at 1 ppm concentration against Cx quinquefasciatus larvae. These compounds may play a useful role in mosquito control by maintaining the vector populations at a minimum level.
