Check Digit Verification of cas no

The CAS Registry Mumber 315179-49-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,5,1,7 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 315179-49:
(8*3)+(7*1)+(6*5)+(5*1)+(4*7)+(3*9)+(2*4)+(1*9)=138
138 % 10 = 8
So 315179-49-8 is a valid CAS Registry Number.

Redox-neutral decarboxylative photocyclization of anthranilic acids

Huang, Huawen,Deng, Kun,Deng, Guo-Jun

supporting information, p. 8243 - 8247 (2020/12/29)

A mild metal-, catalyst-, and oxidant-free photoredox neutral system has been found to efficiently enable intramolecular decarboxylative cyclization of anthranilic acids. This facile protocol provides an alternative method for the synthesis of carbazoles. Mechanistic studies reveal a key photoinduced 6π-electrocyclization process and formic acid was released as the sole byproduct.

Catalytic Asymmetric Chlorocyclization of 2-Vinylphenylcarbamates for Synthesis of 1,4-Dihydro-2H-3,1-benzoxazin-2-one Derivatives

Yu, Yan-Min,Huang, Ya-Nan,Deng, Jun

, p. 1224 - 1227 (2017/03/14)

A facile synthetic approach to a series of chiral 4-chloromethyl-1,4-dihydro-2H-3,1-benzoxazin-2-one derivatives has been described. This transformation is achieved through the catalytic asymmetric chlorocyclization of 2-vinylphenylcarbamates using a newly developed organocatalyst. Furthermore, the resulting products can be easily converted into diverse bioactive agents.

Copper-catalyzed synthesis of triarylamines from aryl halides and arylamines

Qian, Cunwei,Xu, Shaojie,Zong, Qianshou,Fang, Dong

, p. 1881 - 1885 (2012/10/29)

A simple and efficient methodology for the synthesis of triphenylamines has been demonstrated using copper catalyst with a ligand and tripotassium phosphate as the base. The effect of parameters such as catalyst precursors, ligands, bases and solvents were studied and a series of triphenylamines were obtained with moderate to excellent yields in DMF. This reaction displays great functional groups compatibility in the presence of a broad range of functional groups.
