Check Digit Verification of cas no

The CAS Registry Mumber 19857-47-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,8,5 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 19857-47:
(7*1)+(6*9)+(5*8)+(4*5)+(3*7)+(2*4)+(1*7)=157
157 % 10 = 7
So 19857-47-7 is a valid CAS Registry Number.

Palladium-Catalyzed Oxidative Three-Component Coupling of Anthranilamides with Isocyanides and Arylboronic Acids: Access to 2,3-Disubstituted Quinazolinones

Qian, Chun,Liu, Kui,Tao, Shou-Wei,Zhang, Fang-Ling,Zhu, Yong-Ming,Yang, Shi-Lin

, p. 9201 - 9209 (2018/07/13)

A novel palladium-catalyzed oxidative three-component coupling of easily accessible N-substituted anthranilamides with isocyanides and arylboronic acids is achieved. This protocol offers an alternative approach toward 2,3-disubstituted quinazolinones with a wide substrate scope and good functional group tolerance.

Oxidative radical skeletal rearrangement induced by molecular oxygen: Synthesis of quinazolinones

Wang, Yi-Feng,Zhang, Feng-Lian,Chiba, Shunsuke

, p. 2842 - 2845 (2013/07/11)

Oxidative skeletal rearrangement of 5-aryl-4,5-dihydro-1,2,4-oxadiazoles into quinazolinones is induced by molecular oxygen (under a dry air atmosphere) that likely proceeds via transient iminyl radical species. Concise syntheses of biologically active qu

Reinvestigation of the synthesis of 2-benzyl-3-aryl-quinazolin-4-[3H]-ones. An improved multi-component procedure using microwaves
