1346641-23-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1346641-23-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,6,6,4 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1346641-23:
(9*1)+(8*3)+(7*4)+(6*6)+(5*6)+(4*4)+(3*1)+(2*2)+(1*3)=153
153 % 10 = 3
So 1346641-23-3 is a valid CAS Registry Number.

Pd(II)-Catalyzed Enantioselective C(sp3)-H Arylation of Free Carboxylic Acids

Shen, Peng-Xiang,Hu, Liang,Shao, Qian,Hong, Kai,Yu, Jin-Quan

supporting information, p. 6545 - 6549 (2018/05/23)

A monoprotected aminoethyl amine chiral ligand based on an ethylenediamine backbone was developed to achieve Pd-catalyzed enantioselective C(sp3)-H arylation of cyclopropanecarboxylic and 2-aminoisobutyric acids without using exogenous directing groups. This new chiral catalyst affords new disconnection for preparing diverse chiral carboxylic acids from simple starting materials that are complementary to the various ring forming approaches.
