1013905-81-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1013905-81-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,3,9,0 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1013905-81:
(9*1)+(8*0)+(7*1)+(6*3)+(5*9)+(4*0)+(3*5)+(2*8)+(1*1)=111
111 % 10 = 1
So 1013905-81-1 is a valid CAS Registry Number.

Visible light induced the high-efficiency spirocyclization reaction of propynamide and thiophenols via recyclable catalyst Pd/ZrO2

Zhang, Nannan,Zuo, Hangdong,Xu, Chen,Pan, Junyi,Sun, Jun,Guo, Cheng

supporting information, p. 337 - 340 (2019/07/04)

A new method for the synthesis of 3-thioazaspiro[4,5]trienones was developed using Pd nanoparticle catalysts, which are highly efficient, environmentally friendly and recyclable. Alkynes and thiophene phenols are effectively cyclized by Pd/ZrO2

Iodocyclization of n-arylpropynamides mediated by hypervalent iodine reagent: Divergent synthesis of iodinated quinolin-2-ones and spiro[4,5]trienones

Zhou, Ying,Zhang, Xiang,Zhang, Yong,Ruan, Linxin,Zhang, Jiacheng,Zhang-Negrerie, Daisy,Du, Yunfei

, p. 150 - 153 (2017/11/27)

PhI(OCOCF3)2 acts as both a nonmetal oxidant and an iodination reagent to trigger iodocyclization of N-arylpropynamides while selectively affording iodinated quinolin-2-ones or the spiro[4,5]trienone skeleton, depending on the substituent pattern. In cases where the Narylpropynamide bears a para-fluorine on the aniline ring, the spiro compound is formed via an exclusive defluorination process; otherwise, the product was quinolin-2-one.

Catalytic oxidation/C-H functionalization of N-arylpropiolamides by means of gold carbenoids: Concise route to 3-acyloxindoles

Qian, Deyun,Zhang, Junliang

supporting information; experimental part, p. 7082 - 7084 (2012/08/07)

An efficient catalytic C-H functionalization by means of gold carbenoids for the one-step synthesis of 3-acyloxindole derivatives has been developed. The reaction proceeds efficiently with extremely good substrate scope and significant opportunities for s
