2990-01-4 Usage
General Description
1,1-dimethyl-3,3-diphenylurea, also known as fenuron, is a chemical compound commonly used as a herbicide. It is a white crystalline solid with a molecular formula of C13H14N2O. Fenuron works by inhibiting photosynthesis in plants, leading to their death. It is used to control the growth of grasses and weeds in a variety of crops, including cotton, soybeans, and corn. Due to its toxic properties, fenuron should be handled and stored with caution, and protective equipment should be worn when working with it. Additionally, it is important to follow all safety guidelines and local regulations when using fenuron as a herbicide.
Check Digit Verification of cas no
The CAS Registry Mumber 2990-01-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,9 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2990-01:
(6*2)+(5*9)+(4*9)+(3*0)+(2*0)+(1*1)=94
94 % 10 = 4
So 2990-01-4 is a valid CAS Registry Number.

Promotion of reaction of N-H bonds with triarylbismuth and cupric acetate
Chan, Dominic M. T.
, p. 9013 - 9016 (2007/10/03)
Arylation of a diverse group of N-H containing compounds at room temperature with triarylbismuth and cupric acetate in the presence of a tertiary amine promoter, such as triethylamine or pyridine, is described. This mild and highly efficient procedure, which is based on Barton's earlier work on the arylation of amines, can be applied to amides, imides, ureas, carbamates, and sulfonamides.
