Check Digit Verification of cas no

The CAS Registry Mumber 75541-86-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,5,4 and 1 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 75541-86:
(7*7)+(6*5)+(5*5)+(4*4)+(3*1)+(2*8)+(1*6)=145
145 % 10 = 5
So 75541-86-5 is a valid CAS Registry Number.

Asymmetric Synthesis of N-N Axially Chiral Compounds by Phase-Transfer-Catalyzed Alkylations

Pan, Ming,Shao, Ying-Bo,Zhao, Qun,Li, Xin

supporting information, p. 374 - 378 (2022/01/04)

N-N axially chiral skeletons are significant structural motifs in natural products, pharmaceuticals, and functional materials. Herein we disclose a method for the asymmetric synthesis of N-N axially chiral compounds by phase-transfer catalysis. A wide range of N-N axially chiral quinazolinone derivatives were prepared in high yields with excellent stereoselectivities. Furthermore, the synthetic utility of the protocol was proved by large-scale reaction and transformation of the product. Density functional theory calculations provide insight into the mechanism.

Synthesis of some new glutamine linked 2,3-disubstituted quinazolinone derivatives as potent antimicrobial and antioxidant agents

Prashanth,Revanasiddappa

, p. 2665 - 2676 (2013/07/26)

A series of novel glutamine linked 2,3-disubstituted quinazolinone conjugates was synthesized from methyl anthranilate and different substituted acids and acid chlorides. The compounds 5a-l were prepared in good yields. All compounds were screened for their antibacterial activity against Gram-positive and Gram-negative bacteria and for antifungal activity against Candida albicans and Aspergillus flavus using paper disk diffusion technique. The minimum inhibitory concentrations of the compounds were also determined by agar streak dilution method. The compound 5b was found to exhibit the most potent in vitro anti-microbial activity. When tested for their antioxidant activity, compounds 5i and 5l showed potent radical scavenging activity, while compound 5g had moderate effect against 2,2-diphenyl-1-picrylhydrazyl, hydroxyl, nitric oxide, and superoxide radical scavenging assays. These results suggest that, the three quinazolinone analogs (5g, 5i, and 5l) could be considered as useful templates for future development to obtain more potent antioxidant agents.
