139191-69-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 139191-69-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,1,9 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 139191-69:
(8*1)+(7*3)+(6*9)+(5*1)+(4*9)+(3*1)+(2*6)+(1*9)=148
148 % 10 = 8
So 139191-69-8 is a valid CAS Registry Number.

Synthesis and bio-evaluation of natural butenolides-acrylate conjugates

Bao, Longzhu,Wang, Shuangshuang,Song, Di,Wang, Jingjing,Cao, Xiufang,Ke, Shaoyong

, (2019)

A series of novel 3-aryl-4-hydroxy-2(5H) furanone-acrylate hybrids were designed and synthesized based on the natural butenolides and acrylates scaffolds. The structures of the prepared compounds were characterized by 1H-NMR, 13C-NMR and electrospray ionization mass spectrometry (ESI-MS), and the bioactivity of the target compounds against twelve phytopathogenic fungi was investigated. The preliminary in vitro antifungal activity screening showed that most of the target compounds had moderate inhibition on various pathogenic fungi at the concentration of 100 mg·L?1, and presented broad-spectrum antifungal activities. Further studies also indicated that compounds 7e and 7k still showed some inhibitory activity against Pestallozzia theae, Sclerotinia sclerotiorum and Gibberella zeae on rape plants at lower concentrations, which could be optimized as a secondary lead for further research.

A METHOXYL ACRYLIC ESTER FUNGICIDE, THE PREPARATION METHOD AND USES THEREOF

-

, (2011/04/24)

A methoxyl acrylic ester fungicide, the preparation method and uses thereof. The fungicide contains at less the following compound of formula (I) as active ingredient. The fungicide can be further prepared to form the emulsifier oil by mixing with the emulsifier, latent solvent, stabilizer, and solvent. The fungicide is useful for preventing and controlling powdery mildew, downy mildew, gray mold and tan discase of vegetable, melon and fruit, discase of vegetable, melon and fruit cased by Phoma citricarpa, leaf spot of maize, false smut, blossom-end rot of orange and Sclerotinia rot of colza et al. The fungicide has many advantages such as be effect to the strain which produced the resistance, high effect, less toxic and environmrnt-friendly.

METHOXYACRYLATE-BASED FUNGICIDE AND METHODS FOR PREPARING AND USING THE SAME

-

Page/Page column 3, (2010/12/18)

A pharmaceutical composition of fungicide including at least a compound represented by Formula (I). The pharmaceutical composition of fungicide can further include an emulsifier, a cosolvent, a stabilizer, and a solvent. The fungicide can prevent and treat powdery mildew, downy mildew, gray mold, brown spot, scab of vegetables and fruits, southern leaf blight of corn, rice false smut, citrus stem-end rot, and rape sclerotinia rot, with high efficiency, low toxicity, and relative environmental friendliness. A method of preparing the fungicide and a method of using thereof are also provided.
