Check Digit Verification of cas no

The CAS Registry Mumber 305815-25-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,5,8,1 and 5 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 305815-25:
(8*3)+(7*0)+(6*5)+(5*8)+(4*1)+(3*5)+(2*2)+(1*5)=122
122 % 10 = 2
So 305815-25-2 is a valid CAS Registry Number.

A PMMA-based heterogeneous photocatalyst for visible light-promoted [4 + 2] cycloaddition

Blom, Paul W. M.,Ferguson, Calum T. J.,Gehrig, Dominik W.,Huber, Niklas,Landfester, Katharina,Li, Run,Ramanan, Charusheela,Zhang, Kai A. I.

Macromolecular organic photocatalysts consisting of a completely conjugated network have broad and promising applications in visible light-promoted photoredox catalysis. Precise reproduction and control of exact conjugation length remains an important challenge for fully conjugated and macromolecular photocatalysts. Here, we introduce a new photocatalytic material based on classical PMMA copolymerised with defined electron donor and acceptor units with precisely controllable redox potential and conjugation length, creating a promising class of metal-free, stable and low-cost heterogeneous photocatalysts. Furthermore, swelling of the PMMA copolymer matrix in organic solvents led to enhanced substrate diffusion and thereby increased catalytic efficiency. High efficiency and selectivity was achieved for photocatalytic [4 + 2] cycloaddition reactions in air with low effective photocatalyst loading. The photocatalytic efficiency of the PMMA photocatalyst was comparable with the state-of-the-art metal or non-metal catalysts while facilitating easy recyclability.

SINGLE-STEP PROCESS FOR THE PREPARATION OF ARYL OLEFINS

-

Page/Page column 19, (2014/05/24)

The present invention relates to the single-step process for the synthesis of aryl olefin compounds of Formula (1) by reacting aryl aldehydes with alkyl aldehydes in presence of malononitrile and acid or base or salt, optionally in presence of solvent.

Expanding the regioselective enzymatic repertoire: Oxidative mono-cleavage of dialkenes catalyzed by Trametes hirsuta

Paul, Caroline E.,Rajagopalan, Aashrita,Lavandera, Ivan,Gotor-Fernandez, Vicente,Kroutil, Wolfgang,Gotor, Vicente

, p. 3303 - 3305 (2012/04/23)

The first report of a biocatalytic regioselective oxidative mono-cleavage of dialkenes was successfully achieved employing a cell-free enzyme preparation from Trametes hirsuta at the expense of molecular oxygen. Selected reactions were performed on a preparative scale affording high to excellent conversions and chemoselectivities. The Royal Society of Chemistry 2012.
