Check Digit Verification of cas no

The CAS Registry Mumber 10229-63-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,2,2 and 9 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 10229-63:
(7*1)+(6*0)+(5*2)+(4*2)+(3*9)+(2*6)+(1*3)=67
67 % 10 = 7
So 10229-63-7 is a valid CAS Registry Number.

Aliphatic nitro compounds chemistry: oximes–nitrones tunable production through directed tandem synthesis

Kazemi, Foad,Ramdar, Moosa,Davarpanah, Jamal

, p. 353 - 362 (2019)

Abstract: Reduction of aliphatic nitro compounds in the presence of aldehydes and dialdehydes for tunable directed synthesis of oximes, nitrones, nitrone–oximes, and dinitrones was reported. The slow and nonselective reduction of aliphatic nitro compounds was directed by condensation of in situ prepared alkylhydroxylamines with aromatic aldehydes. Mononitrones and dinitrones were synthesized at reflux and at 55?°C conditions, respectively, in tetrahydrofuran using SnCl2?2H2O and Na2CO3. It was found that the presence of a catalytic amount of carboxylic acid such as 3-phenylpropanoic acid increases the yield of dinitrones versus nitrone–oxime and dioxime when dialdehydes were used as aldehyde source.

1-Cyanoformamidines. Formation during the RuO4-mediated oxidation of secondary amines

Florea, Cristina,Stavarache, Cristina,Petride, Horia

, p. 319 - 325 (2016/10/11)

When performed in the presence of cyanide and at pH smaller than 5, the RuO4-mediated oxidation of secondary amines Bn-NH-R (1a-b; R=Me, Et) gave mainly 1-cyanoformamidines Bn-NR-C(=NH)-CN (2a-b) and their hydrolysis products Bn-NR-COCN (3a-b), Bn-NR-CN (4a-b), Bn-NR-CONH2 (5a-b). Carboxamides 5a-b can result also directly from 1a-b. (Chemical Equation Presented).

Stereoselective synthesis of fluoroalkenoates and fluorinated isoxazolidinones: N-substituents governing the dual reactivity of nitrones

Prakash, G.K. Surya,Zhang, Zhe,Wang, Fang,Rahm, Martin,Ni, Chuanfa,Iuliucci, Marc,Haiges, Ralf,Olah, George A.

supporting information, p. 831 - 838 (2014/01/23)

α-Fluoroalkenoates and 4-fluoro-5-isoxazolidinones are of vast interest due to their potential biological applications. We now demonstrate the syntheses of (E)-α-fluoroalkenoates and 4-fluoro-5-isoxazolidinones by the reactions between nitrones and α-fluoro-α-bromoacetate. By altering N-substituents in nitrones, (E)-α-fluoroalkenoates and 4-fluoro-5-isoxazolidinones can be achieved, respectively, with high chemo- and stereoselectivities. Experimental and computational studies have been conducted to elucidate the reaction mechanisms. Linear free energy relationship studies further revealed that the N-substituent effects are primarily of electronic origin. Copyright
