1873-62-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1873-62-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,7 and 3 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1873-62:
(6*1)+(5*8)+(4*7)+(3*3)+(2*6)+(1*2)=97
97 % 10 = 7
So 1873-62-7 is a valid CAS Registry Number.

Reaction of Tertiary 2-Chloroketones with Cyanide Ions: Application to 3-Chloroquinolinediones

Bedná?, Luká?,Kafka, Stanislav,Klásek, Antonín,Ly?ka, Antonín,Rouchal, Michal,Rudolf, Ond?ej

, p. 645 - 652 (2021/07/22)

3-Chloroquinoline-2,4-diones react with cyanide ions in dimethyl formamide to give 3-cyanoquinoline-2,4-diones in small yields due to the strong hindrance of the substituent at the C-3 atom. Good yields can be achieved if the substituent at this position

Oxidative ring opening of 3-hydroxyquinoline-2,4(1H,3H)-diones into N-(α-ketoacyl)anthranilic acids Dedicated to Professor Slovenko Polanc on his 65th birthday

Kafka, Stanislav,Proisl, Karel,Ka?párková, Věra,Urankar, Damijana,Kimmel, Roman,Ko?mrlj, Janez

, p. 10826 - 10835 (2014/01/06)

N-(α-Ketoacyl)anthranilic acids were prepared by oxidative ring opening of 3-hydroxyquinoline-2,4(1H,3H)-diones by using paraperiodic acid (H5IO6) or sodium periodate (NaIO4). The optimisation of the reaction conditions is

Modified riemschneider reaction of 3-thiocyanatoquinolinediones

Rudolf, Ondrej,Mrkvicka, Vladimir,Lycka, Antonin,Rouchal, Michal,Klasek, Antonin

experimental part, p. 1352 - 1372 (2012/09/25)

The Riemschneider reaction of 3-thiocyanatoquinoline-2,4(1H,3H)-diones with conc. H2SO4 was investigated. Using different reaction conditions, 13 types of reaction products were isolated. Compounds bearing a Me, Et, or Bu group at C(3) afforded mainly [1,3]thiazolo[5,4-c]quinoline-2,4- diones and 1,9b-dihydro-9b-hydroxythiazolo[5,4-c]quinoline-2,4-diones. In the case of the 3-Bu derivatives of the starting compounds, C-debutylation was also observed. If a Bn group is present at C(3), rapid C-debenzylation of the starting thiocyanates occurred, yielding [1,3]oxathiolo[4,5-c]quinoline-2,4- diones, and mixtures of mono-, di-, and trisulfides derived from 4-hydroxy-3-sulfanylquinoline-2-ones. The reaction mechanism of all of the transformations is discussed. All new compounds were characterized by IR, 1H- and 13C-NMR, and EI and ESI mass spectra, and in some cases, 15N-NMR spectra were also used to characterize new compounds. Copyright
