189031-66-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 189031-66-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,0,3 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 189031-66:
(8*1)+(7*8)+(6*9)+(5*0)+(4*3)+(3*1)+(2*6)+(1*6)=151
151 % 10 = 1
So 189031-66-1 is a valid CAS Registry Number.

Preference of Ruthenium-Based Metathesis Catalysts toward Z- and E-Alkenes as a Guide for Selective Reactions to Alkene Stereoisomers

Lee, Jihong,Kim, Kyung Hwan,Lee, Ok Suk,Choi, Tae-Lim,Lee, Hee-Seung,Ihee, Hyotcherl,Sohn, Jeong-Hun

, p. 7591 - 7596 (2016/09/09)

As a guide for selective reactions toward either Z- or E-alkene in a metathesis reaction, the relative preference of metathesis Ru catalysts for each stereoisomer was determined by a method using time-dependent fluorescence quenching. We found that Ru-1 p

Ti-catalyzed straightforward synthesis of exocyclic allenes

Munoz-Bascon, Juan,Hernandez-Cervantes, Carmen,Padial, Natalia M.,Alvarez-Corral, Miriam,Rosales, Antonio,Rodriguez-Garcia, Ignacio,Oltra, J. Enrique

supporting information, p. 801 - 810 (2014/01/23)

Exocyclic allenes constitute useful building blocks in organic synthesis and have recently been identified as key intermediates in the synthesis of natural products. Here the first general method for the most straightforward synthesis of exocyclic allenes

Secondary phosphine oxide-gold(I) complexes and their first application in catalysis

Schroeder, Felix,Tugny, Coralie,Salanouve, Elise,Clavier, Herve,Giordano, Laurent,Moraleda, Delphine,Gimbert, Yves,Mouries-Mansuy, Virginie,Goddard, Jean-Philippe,Fensterbank, Louis

supporting information, p. 4051 - 4056 (2014/10/15)

A series of new secondary phosphine oxide (SPO)-gold(I) complexes have been synthesized and characterized by X-ray crystallography. Complexes exhibited dimeric structures interconnected by O-H···Cl hydrogen bonds. Their first use in homogeneous catalysis
