1430074-80-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1430074-80-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,0,0,7 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1430074-80:
(9*1)+(8*4)+(7*3)+(6*0)+(5*0)+(4*7)+(3*4)+(2*8)+(1*0)=118
118 % 10 = 8
So 1430074-80-8 is a valid CAS Registry Number.

Metal-free synthesis of imidazo[1,5- a] pyridines via elemental sulfur mediated sequential dual oxidative Csp3-H amination

Sheng, Jie,Liu, Jidan,Zhao, He,Zheng, Liyao,Wei, Xingchuan

supporting information, p. 5570 - 5574 (2018/08/17)

A simple and efficient approach has been developed for the synthesis of imidazo[1,5-a]pyridines using the elemental sulfur mediated sequential dual oxidative Csp3-H amination of 2-pyridyl acetates and amines under metal- and peroxide-free conditions. Broad substrate scope, operational simplicity and gram-scale ability make this chemistry very practical.

Mild metal-free sequential dual oxidative amination of C(sp3)-H bonds: Efficient synthesis of imidazo[1,5-a]pyridines

Yan, Yizhe,Zhang, Yonghui,Zha, Zhenggen,Wang, Zhiyong

supporting information, p. 2274 - 2277 (2013/06/05)

A metal-free sequential dual oxidative amination of C(sp3)-H bonds under ambient conditions was the first developed, affording imidazo[1,5-a]pyridines in good to excellent yields. The reaction was involved in two oxidative C-N couplings and one oxidative dehydrogenation process with six hydrogen atoms removed.
