2281-78-9 Usage
General Description
1-(4-chlorophenyl)sulfonyl-3-propan-2-yl-urea is a chemical compound with the molecular formula C11H15ClN2O3S. It is a derivative of urea and is commonly used as a herbicide in the agriculture industry. This chemical works by inhibiting the photosynthetic system II electron transport in target plants, leading to their eventual death. It is effective against a broad spectrum of weeds and is often used in combination with other herbicides to enhance its effectiveness. However, care should be taken when handling this chemical as it can be toxic to aquatic organisms and may have adverse effects on human health if not used properly.
Check Digit Verification of cas no
The CAS Registry Mumber 2281-78-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,8 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2281-78:
(6*2)+(5*2)+(4*8)+(3*1)+(2*7)+(1*8)=79
79 % 10 = 9
So 2281-78-9 is a valid CAS Registry Number.

A facile synthesis of sulfonylureas: Via water assisted preparation of carbamates
Tanwar, Dinesh Kumar,Ratan, Anjali,Gill, Manjinder Singh
, p. 4992 - 4999 (2017/07/11)
A novel and simple approach to the synthesis of sulfonylureas has been reported. It involved the reaction of various amines with diphenyl carbonate to yield the corresponding carbamates, which subsequently reacted with different sulphonamides to produce different sulfonylureas in excellent yields. The first reaction of diphenyl carbonate with amines was carried out in aqueous:organic (H2O:THF, 90:10) medium at room temperature to produce carbamates that paved a straightforward route to sulfonylureas after reaction with sulfonamides. The above process avoided traditional multistep protocols and the use of hazardous, irritant, toxic and moisture sensitive reagents such as phosgene, isocyanates and/or chloroformates.
