Check Digit Verification of cas no

The CAS Registry Mumber 221121-34-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,1,2 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 221121-34:
(8*2)+(7*2)+(6*1)+(5*1)+(4*2)+(3*1)+(2*3)+(1*4)=62
62 % 10 = 2
So 221121-34-2 is a valid CAS Registry Number.

Development of a scalable synthesis of mevidalen (LY3154207), an orally available positive allosteric modulator of the human dopamine D1 receptor

Cole, Kevin P.,DeBaillie, Amy C.,Garcia, Conchita F.,Hao, Junliang,Houghton, Peter,Huang, Ping,Jia, Mo,Kadlecikova, Katarina,Liu, Peng,Piper, Jared,Richards, Daniel S.,Richardson, Jeffery,Rizzo, John

, p. 2549 - 2564 (2020)

The evolution from early medicinal chemistry to large-scale production of the chemical synthesis of Lilly D1-positive allosteric modulator (PAM) mevidalen (LY3154207) and its hydroxybenzoate co-crystal is outlined. The issues and steps taken to resolve them are outlined across several generations of synthesis, including unexpected issues that arose during cryogenic addition of MeLi to a key imine intermediate and the use of flow chemistry to enable large-scale production. Ultimately, a process that was used to deliver >100 kg of API to support ongoing clinical trials is described.

Synthesis and biological evaluation of novel 2-(substituted phenylaminocarbonylmethylthio)-6-(2,6-dichlorobenzyl)-pyrimidin-4(3H)-ones as potent HIV-1 NNRTIs

Yu, Mingyan,Liu, Xinyong,Li, Zhenyu,Liu, Shuai,Pannecouque, Christophe,Clercq, Erik De

experimental part, p. 7749 - 7754 (2010/03/03)

A series of novel 2-(phenylaminocarbonylmethylthio)-6-(2,6-dichlorobenzyl)-pyrimidin-4(3H)-ones have been designed and synthesized. All of the new compounds were evaluated for their anti-HIV activities in MT-4 cells. Most of these new compounds showed mod

Parallel solution-phase and microwave-assisted synthesis of new S-DABO derivatives endowed with subnanomolar anti-HIV-1 activity

Manetti, Fabrizio,Esté, José A.,Clotet-Codina, Imma,Armand-Ugón, Mercedes,Maga, Giovanni,Crespan, Emmanuele,Cancio, Reynel,Mugnaini, Claudia,Bernardini, Cesare,Togninelli, Andrea,Carmi, Caterina,Alongi, Maddalena,Petricci, Elena,Massa, Silvio,Corelli, Federico,Botta, Maurizio

, p. 8000 - 8008 (2007/10/03)

A simple and efficient methodology for the parallel solution-phase synthesis has been set up to obtain a series of thiouracils, in turn selectively S-benzylated under microwave irradiation to give new S-DABOs. Biological screening led to the identificatio
