70729-31-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 70729-31-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,7,2 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 70729-31:
(7*7)+(6*0)+(5*7)+(4*2)+(3*9)+(2*3)+(1*1)=126
126 % 10 = 6
So 70729-31-6 is a valid CAS Registry Number.

Investigation of the Organocatalytic Chlorination of 2-Phenylpropanal

Mohr, Lisa-Marie,McCulley, Christina H.,Blom, Jakob,Lamhauge, Johannes N.,Anker J?rgensen, Karl

supporting information, p. 17465 - 17475 (2021/10/25)

Results of an examination of the organocatalytic enantioselective α-chlorination of 2-phenylpropanal are described. Synthetic investigation including the screening of primary and secondary aminocatalysts, many different reaction conditions, and other α-br

The Rabe amination after a century: Direct addition of N-heterocycles to carbonyl compounds

Scarpino Schietroma, Daniele M.,Monaco, Mattia R.,Bucalossi, Valerio,Walter, Philipp E.,Gentili, Patrizia,Bella, Marco

scheme or table, p. 4692 - 4695 (2012/08/08)

A catalytic version of the Rabe electrophilic amination is presented. This kind of reaction was originally employed in 1918 in a key step for the conversion of quinotoxine to quinine. Ketones and α-substituted aldehydes give the corresponding α-aminated carbonyl compounds in moderate yield. α,α-Unsubstituted aldehydes give rise to amino ketones via a novel rearrangement.

Polymer-supported 4-(phenylseleno)morpholine as a useful α-selenenylating agent for saturated aldehydes. A highly efficient route to α-haloaldehydes on solid phase
