Check Digit Verification of cas no

The CAS Registry Mumber 395639-04-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,5,6,3 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 395639-04:
(8*3)+(7*9)+(6*5)+(5*6)+(4*3)+(3*9)+(2*0)+(1*4)=190
190 % 10 = 0
So 395639-04-0 is a valid CAS Registry Number.

Diversely Substituted Quinolines via Rhodium-Catalyzed Alkyne Hydroacylation

Neuhaus, James D.,Morrow, Sarah M.,Brunavs, Michael,Willis, Michael C.

supporting information, p. 1562 - 1565 (2016/05/02)

The Rh-catalyzed hydroacylative union of aldehydes and o-alkynyl anilines leads to 2-aminophenyl enones, and onward to substituted quinolines. The mild reaction conditions employed in this chemistry result in a process that displays broad functional group

Indole-3-acetic acids and hetero analogues by one pot synthesis including Heck cyclisation

Wensbo, David,Annby, Ulf,Gronowitz, Salo

, p. 10323 - 10342 (2007/10/02)

Bz-substituted indole-3-acetic acid ethyl esters (14e-g) and heteroanalogues, i.e. thienopyrroles (14a,c) and selenolopyrrole (14d), were prepared starting from N-BOC protected o-iodo aryl amines. Allylation with ethyl 4-bromocrotonate, followed by palladium-catalysed ring closure in a one pot reaction, yielded N-BOC protected indoles (13e-g), thienopyrroles (13a-c), and selenolopyrrole (13d). The BOC group was readily removed thermally after adsorption on silica. Oxothienopyrroles (11a-c) were similarly prepared.
