Check Digit Verification of cas no

The CAS Registry Mumber 99321-88-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,3,2 and 1 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 99321-88:
(7*9)+(6*9)+(5*3)+(4*2)+(3*1)+(2*8)+(1*8)=167
167 % 10 = 7
So 99321-88-7 is a valid CAS Registry Number.

Palladium nano-particles as a recyclable catalyst for C-O bond formation under solvent free conditions

Khan, Ajmal,Zhang, Junjie,Khan, Shahid

, p. 4116 - 4120 (2020)

The development of green, economical and sustainable chemical processes is one of the primary challenges in organic chemistry. Herein, we report a recoverable heterogeneous palladium catalyst for the stereoselective synthesis of multi-functionalized allylic ethers under solvent free conditions. This method is based on in situ generated PdNP catalyzed O-allylation of alcohols with vinyl cyclic carbonates. Solvent-free conditions, easily recoverable catalysts, efficient recycling, and operational simplicity make the protocol green, economic and sustainable.

Pd-Catalyzed Enantio- and Regioselective Formation of Allylic Aryl Ethers

Xie, Jianing,Guo, Wusheng,Cai, Aijie,Escudero-Adán, Eduardo C.,Kleij, Arjan W.

supporting information, p. 6388 - 6391 (2017/12/08)

A general methodology for the synthesis of enantioenriched tertiary allylic aryl ethers through Pd-catalyzed decarboxylative reactions of vinyl cyclic carbonates and phenols is presented. Switching of the regioselectivity toward the formation of linear products by a judicious choice of the ligand is also reported.
