Check Digit Verification of cas no

The CAS Registry Mumber 898138-80-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,8,1,3 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 898138-80:
(8*8)+(7*9)+(6*8)+(5*1)+(4*3)+(3*8)+(2*8)+(1*0)=232
232 % 10 = 2
So 898138-80-2 is a valid CAS Registry Number.

(: Z)-Selective anti-Markovnikov or Markovnikov thiol-yne-click reactions of an internal alkyne by amide hydrogen bond control

Pramanik, Milan,Choudhuri, Khokan,Chakraborty, Subhayan,Ghosh, Arindam,Mal, Prasenjit

, p. 2991 - 2994 (2020)

Herein, we show exclusive control of stereo and regioselective thiol-yne click (TYC) reactions of internal alkynes via amide hydrogen bond control. By exploiting appropriate hydrogen bonding interactions like N-H?S, N-H?N and C-H?O, either (Z)-selective anti-Markovnikov or Markovnikov products could be obtained for an internal alkyne, exclusively.

One-pot synthesis of a white-light emissive bichromophore operated by aggregation-induced dual emission (AIDE) and partial energy transfer

Biesen, Lukas,Deni?en, Melanie,Hannen, Ricarda,Hoffmann, Katrin,Itskalov, Dana,Müller, Thomas J. J.,Nirmalananthan-Budau, Nithiya,Reiss, Guido J.,Resch-Genger, Ute

supporting information, p. 7407 - 7410 (2020/07/15)

Merocyanine-triarylamine bichromophores are readily synthesized by sequentially Pd-catalyzed insertion-alkynylation-Michael-Suzuki four-component reactions. White-light emissive systems form upon aggregation in 1 : 99 and 0.1 : 99.9 vol percent CH2Cl2-cyclohexane mixtures, ascribed to aggregation-induced dual emission (AIDE) in combination with partial energy transfer between both chromophore units as supported by spectroscopic studies.

Access to 3-(2-Oxoalkyl)-azaspiro[4.5]trienones via Acid-Triggered Oxidative Cascade Reaction through Alkenyl Peroxide Radical Intermediate

Wang, Chang-Sheng,Roisnel, Thierry,Dixneuf, Pierre H.,Soulé, Jean-Fran?ois

supporting information, p. 445 - 450 (2019/01/04)

Azaspiro[4.5]trienones bearing ketone side chains at the 3-position are prepared from N-alkyl-arylpropiolamides and ketones via oxidative 1,2-difunctionalization of alkynes. The cascade sequence starts with the generation of alkenyl peroxide intermediates

Palladium-Catalyzed Tandem Approach to 3-(Diarylmethylene)oxindoles Using Microwave Irradiation

Park, Sunhwa,Shin, Kye Jung,Seo, Jae Hong

supporting information, p. 2296 - 2300 (2015/09/28)

We developed a rapid and efficient microwave-assisted tandem reaction for the synthesis of 3-(diarylmethylene)oxindoles. Three palladium-catalyzed reactions (Sonogashira, Heck, and Suzuki-Miyaura reactions) were combined under microwave irradiation conditions to produce 3-(diarylmethylene)oxindoles from simple propiolamides, aryl iodides, and arylboronic acids. The addition of Ag3PO4 enhanced the yield and stereoselectivity of the tandem reaction significantly.

Copper-Catalyzed Domino Synthesis of Benzo[4,5]imidazo[1,2-a]pyrimidin-4(10H)-ones using Cyanamide as a Building Block

Lou, Zhenbang,Wu, Xudong,Yang, Haijun,Zhu, Changjin,Fu, Hua

supporting information, p. 3961 - 3968 (2016/01/25)

An efficient and practical copper-catalyzed domino synthesis of benzo[4,5]imidazo[1,2-a]pyrimidin-4(10H)-ones has been developed. The protocol uses N-(2-halophenyl)-3-alkylpropiolamides and cyanamide as the starting materials, inexpensive copper(I) iodide and pipecolinic acid as the catalyst and ligand, and the corresponding products were obtained in moderate to good yields.

Synthesis of 3-(diarylmethylene)oxindoles via a palladium-catalyzed one-pot reaction: Sonogashira-heck-suzuki-miyaura combined reaction

Dong, Guang Ri,Park, Sunhwa,Lee, Dahye,Shin, Kye Jung,Seo, Jae Hong

supporting information, p. 1993 - 1997 (2013/09/24)

A novel one-pot reaction for the synthesis of 3-(diarylmethylene)oxindoles is described. The reaction involves the successive combination of three palladium-catalyzed reactions (Sonogashira, Heck, and Suzuki-Miyaura reactions). This method enables the rapid synthesis of various 3-(diarylmethylene)oxindoles from simple propiolamides. The addition of silver salts dramatically enhanced the E/Z stereoselectivity of the reaction. Georg Thieme Verlag Stuttgart, New York.
