1328889-67-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1328889-67-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,8,8,8 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1328889-67:
(9*1)+(8*3)+(7*2)+(6*8)+(5*8)+(4*8)+(3*9)+(2*6)+(1*7)=213
213 % 10 = 3
So 1328889-67-3 is a valid CAS Registry Number.

A Tetraarylpyrrole-Based Phosphine Ligand for the Palladium-Catalyzed Amination of Aryl Chlorides

Sai, Masahiro

supporting information, p. 5422 - 5428 (2021/10/08)

A tetraarylpyrrole-based phosphine ligand L1 in combination with Pd(dba)2 provided a catalyst for the Buchwald-Hartwig amination reaction. A variety of amines were rapidly coupled with aryl chlorides at a Pd loading of 0.5 mol%. The selective monoarylation of aliphatic primary amines was achieved in the presence of 0.8 equiv. water. Comparison experiments were also conducted, which revealed that the catalytic activity of L1 is superior to representative phosphine ligands in the Pd-catalyzed C?N coupling of various amines. (Figure presented.).

Silver-catalyzed intramolecular chloroamination of allenes: Easy access to functionalized 3-pyrroline and pyrrole derivatives

Sai, Masahiro,Matsubara, Seijiro

supporting information; experimental part, p. 4676 - 4679 (2011/11/06)

A 1,10-phenanthroline-ligated cationic silver complex allows the intramolecular chloroamination of allenes with N-chlorosuccinimide using 2,6-lutidine as a base. This process proceeds under mild conditions and can tolerate a variety of functional groups.
