40757-12-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40757-12-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,7,5 and 7 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 40757-12:
(7*4)+(6*0)+(5*7)+(4*5)+(3*7)+(2*1)+(1*2)=108
108 % 10 = 8
So 40757-12-8 is a valid CAS Registry Number.

Direct C-H Cyanation of Arenes via Organic Photoredox Catalysis

McManus, Joshua B.,Nicewicz, David A.

, p. 2880 - 2883 (2017/03/11)

Methods for the direct C-H functionalization of aromatic compounds are in demand for a variety of applications, including the synthesis of agrochemicals, pharmaceuticals, and materials. Herein, we disclose the construction of aromatic nitriles via direct C-H functionalization using an acridinium photoredox catalyst and trimethylsilyl cyanide under an aerobic atmosphere. The reaction proceeds at room temperature under mild conditions and has proven to be compatible with a variety of electron-donating and -withdrawing groups, halogens, and nitrogen- and oxygen-containing heterocycles, as well as aromatic-containing pharmaceutical agents.

Iron(II)-catalyzed direct cyanation of arenes with aryl(cyano)iodonium triflates

Shu, Zhibin,Ji, Wenzhi,Wang, Xi,Zhou, Yujing,Zhang, Yan,Wang, Jianbo

supporting information, p. 2186 - 2189 (2014/03/21)

A direct oxidative cyanation of arenes under FeII catalysis with 3,5-di(trifluoromethyl)phenyl(cyano)iodonium triflate (DFCT) as the cyanating agent has been developed. The reaction is applicable to wide range of aromatic substrates, including polycyclic structures and heteroaromatic compounds. Copyright
