Check Digit Verification of cas no

The CAS Registry Mumber 20821-91-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,2 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 20821-91:
(7*2)+(6*0)+(5*8)+(4*2)+(3*1)+(2*9)+(1*1)=84
84 % 10 = 4
So 20821-91-4 is a valid CAS Registry Number.

Microwave-assisted synthesis, in silico ADME prediction and antibacterial study of 2-(substituted acetamido)-5-nitrobenzophenone derivatives

Li, Tiangang,Singh, Sandeep,Zhai, Xing,Meng, Xiangqi,Singh, Rajesh K.

, p. 2452 - 2456 (2015)

A series of novel 2-amino-5-nitrobenzophenone derivatives (3-10) were synthesized and characterized by IR, 1H NMR and CHN elemental studies. All the synthesized compounds were subjected to in silico ADME predictions for determination for drug like properties. The values of physico-chemical parameters like molecular weight, nON value, nOHNH value, n-violations and the number of rotatable bonds of all the synthesized compounds also lies between the ranges that are required for good bioavailability. The synthesized compounds were tested for their in vitro antibacterial activity against the Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli) bacteria. Among all the compounds synthesized compounds 4, 9, 10 have shown the maximum antibacterial activity in their group whereas compounds 3, 6, 8 have shown the minimum antibacterial activity.

Preparation method of 2-chloracetylamino-5-nitro benzophenone

-

Paragraph 0015; 0016; 0017; 0018; 0019, (2017/03/14)

The invention provides a preparation method of 2-chloracetylamino-5-nitro benzophenone. The method comprises: taking 2-amino-5-nitro benzophenone and chloroacetyl chloride as raw materials, and performing an acylation reaction in an organic solvent for 1-3.5 h, wherein the acylation reaction is carried out in a reflux condition, the raw material ratio of 2-amino-5-nitro benzophenone to chloroacetyl chloride to the organic solvent is 50 g to (16-48.5) ml to (1000-2000) ml, and the organic solvent is a mixed solvent of cyclohexane and toluene with the volume ratio of cyclohexane to toluene being 1:1-2; and after the acylation reaction is finished, reducing the temperature to the room temperature, performing filtration, washing the obtained filter residue with water till the filter residue is neutral, and performing drying to obtain 2-chloracetylamino-5-nitro benzophenone. Compared with a preparation method in the prior art, the preparation method is reasonable in processing step design, good in operability, and less in by-products. The obtained product is high in purity and yield, and the method can meet industrial application requirements.
