53244-19-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 53244-19-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,2,4 and 4 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 53244-19:
(7*5)+(6*3)+(5*2)+(4*4)+(3*4)+(2*1)+(1*9)=102
102 % 10 = 2
So 53244-19-2 is a valid CAS Registry Number.

Non-reductive decyanation reactions of disubstituted malononitrile derivatives promoted by NaHMDS

Domon, Daisuke,Iwakura, Masaru,Tanino, Keiji

, p. 1957 - 1960 (2017)

A new method for achieving the decyanation of disubstituted malononitrile derivatives without using reducing agents has been developed. Treatment of a six-membered malononitrile derivative with NaHMDS followed by methanol afforded the corresponding acetonitrile derivative in high yield. The present method was applicable to the decyanation reactions of a variety of malononitriles including four- and five-membered compounds as well as acyclic ones.

Anodic benzylic C(sp3)-H amination: Unified access to pyrrolidines and piperidines

Herold, Sebastian,Bafaluy, Daniel,Mu?iz, Kilian

supporting information, p. 3191 - 3196 (2018/07/29)

An electrochemical aliphatic C-H amination strategy was developed to access the important heterocyclic motifs of pyrrolidines and piperidines within a uniform reaction protocol. The mechanism of this unprecedented C-H amination strategy involves anodic C-H activation to generate a benzylic cation, which is efficiently trapped by a nitrogen nucleophile. The applicability of the process is demonstrated for 40 examples comprising both 5- and 6-membered ring formations.
