144978-77-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 144978-77-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,9,7 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 144978-77:
(8*1)+(7*4)+(6*4)+(5*9)+(4*7)+(3*8)+(2*7)+(1*7)=178
178 % 10 = 8
So 144978-77-8 is a valid CAS Registry Number.

SPANphos ligands in palladium-catalyzed asymmetric fluorination

Jacquet, Olivier,Clement, Nicolas D.,Blanco, Carolina,Belmonte, Marta Martinez,Benet-Buchholz, Jordi,Van Leeuwen, Piet W. N. M.

experimental part, p. 4844 - 4852 (2012/10/18)

The synthesis of new enantiopure wide-bite-angle diphosphanes is described as well as their use in the palladium-catalyzed asymmetric fluorination of α-cyanoacetates. Enantiomeric excesses up to 93 % were obtained when Pd(OAc)2-SPANphos was use

Qi, Chenze,Shao, Linjun,Lu, Yueqing,Wang, Chen,Zhang, Xian-Man

body text, p. 523 - 528 (2012/07/28)

An experimental approach was developed to determine the intrinsic thermolysis rate constants of the central carbon-carbon bond during the dl/meso isomerization of diethyl 2,3-dicyano-2,3-di(p-substituted phenyl)succinates (G=H, Me, OMe, Cl, and NO2/

Potassium fluoride on alumina: Oxidative coupling of acidic carbon compounds with diiodine

Villemin,Alloum

, p. 3169 - 3179 (2007/10/02)

Diiodine reacts at room temperature with activated methylene compounds in the presence of potassium fluoride on alumina and saturated dimers, unsaturated dimers or trimers were formed according to the stoechiometry of the reaction. The reactions were improved by using ultrasound activation.

The C-Arylation of α-Cyano Esters and Malononitriles by Aryllead(IV) Triacetates

Kozyrod, Robert P.,Morgan, Jacqueline,Pinhey, John T.
