56182-25-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 56182-25-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,1,8 and 2 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 56182-25:
(7*5)+(6*6)+(5*1)+(4*8)+(3*2)+(2*2)+(1*5)=123
123 % 10 = 3
So 56182-25-3 is a valid CAS Registry Number.

Chiral N,N Ligands Enabling Palladium-Catalyzed Enantioselective Intramolecular Heck–Matsuda Carbonylation Reactions by Sequential Migratory and CO Insertions

Carmona, Rafaela C.,K?ster, Otto D.,Correia, Carlos Roque Duarte

, p. 12067 - 12070 (2018/09/11)

Unprecedented enantioselective intramolecular Heck carbonylation reactions of arenediazonium salts were enabled by a chiral N,N ligand. This reaction constitutes the first enantioselective Heck carbonylation that proceeds through migratory insertion followed by CO insertion. The enantioenriched functionalized dihydrobenzofurans were obtained in good to high yields and enantiomeric ratios of up to 98:2 under mild and operationally simple reaction conditions.
