Check Digit Verification of cas no

The CAS Registry Mumber 30160-12-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,1,6 and 0 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 30160-12:
(7*3)+(6*0)+(5*1)+(4*6)+(3*0)+(2*1)+(1*2)=54
54 % 10 = 4
So 30160-12-4 is a valid CAS Registry Number.

Rawal's catalyst as an effective stimulant for the highly asymmetric Michael addition of β-keto esters to functionally rich nitro-olefins

Suresh Kumar,Prabhakar Reddy,Madhavachary,Ramachary, Dhevalapally B.

, p. 5494 - 5499 (2016)

A general approach to asymmetric synthesis of highly substituted dihydroquinolines was achieved through neighboring ortho-amino group engaged sequential Michael/amination/dehydration reactions on (E)-2-(2-nitrovinyl)anilines with cyclic and acyclic β-keto esters in the presence of a catalytic amount of Rawal's quinidine-NH-benzyl squaramide followed by TFA.

Quinoline derivative as well as preparation method and application thereof

Paragraph 0137-0144, (2021/07/17)

The invention belongs to the technical field of chemical drug synthesis, and particularly relates to a quinoline derivative as well as a preparation method and application thereof. In a reaction system, firstly, a metal catalyst, a ligand and a silicon hydrogen reagent interact to generate metal hydride, the metal hydride and an alkyne compound are subjected to addition, the metal hydride and an anthranil compound are subjected to an electrophilic amination reaction, and then the polysubstituted quinoline derivative is obtained through intramolecular cyclization. According to the invention, the starting raw materials such as the alkyne and the anthranil compound of the reaction are cheap and easily available, a variety of different polysubstituted quinoline derivatives can be constructed by using the one-step method, and can be rapidly converted into other compounds through the oxidation, the reduction, the coupling and other approaches of the target molecule so as to provide the good application prospect in the fields of drug development and material preparation; and the method is mild in condition, green, efficient, simple to operate and very suitable for large-scale industrial production.

An efficient heterogeneous gold(I)-catalyzed intermolecular cycloaddition of 2-aminoaryl carbonyls and internal alkynes leading to polyfunctionalized quinolines

Hu, Wenli,Yang, Weisen,Yan, Tao,Cai, Mingzhong

supporting information, p. 799 - 813 (2019/03/23)

The first heterogeneous intermolecular cycloaddition of 2-aminoaryl carbonyls and internal alkynes was realized in DMF at 100 °C by using a triphenylphosphine-functionalized MCM-41-supported gold(I) complex [MCM-41-PPh3-AuCl] and AgOTf as catal
