N-(Chloro-phenyl-methylene)-4-methyl-benzenesulfonamide, also known as Chlorsulfuron, is a widely used herbicide belonging to the sulfonylurea class. It is effective in controlling various broadleaf and grassy weeds by inhibiting the enzyme acetohydroxyacid synthase, which is crucial for plant growth. This chemical is particularly useful in crops like cereals, sugarcane, and turf grass, as it offers selective weed control without harming the desired plants. Chlorsulfuron is known for its low use rates and long residual activity, making it an efficient choice for agricultural applications. However, it is important to follow proper application guidelines to minimize potential environmental impacts and ensure the safety of non-target species.

Check Digit Verification of cas no

The CAS Registry Mumber 4513-27-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,1 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4513-27:
(6*4)+(5*5)+(4*1)+(3*3)+(2*2)+(1*7)=73
73 % 10 = 3
So 4513-27-3 is a valid CAS Registry Number.

Synthesis of 2-Imidazolines via Palladium-Catalyzed Cyclization Reaction of 2,3-Allenyl Amines and Aryl Iodides

Fang, Zixuan,Hu, Jinxing,Liang, Xiaoxia,Liu, Yanjun,Liu, Yue,Lu, Rongmei,Wang, Shaoyu,Zeng, Xianzhong,Zhang, Cheng

supporting information, p. 901 - 908 (2020/03/13)

An effective method for the synthesis of polysubstituted 2-imidazoline derivatives via palladium-catalyzed cyclization of 2,3-allenyl amines with aryl iodides is described. This pure domino process allows the formation of new carbon-carbon and carbon-nitrogen bonds in a single synthetic operation.
