42240-17-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 42240-17-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,2,4 and 0 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 42240-17:
(7*4)+(6*2)+(5*2)+(4*4)+(3*0)+(2*1)+(1*7)=75
75 % 10 = 5
So 42240-17-5 is a valid CAS Registry Number.

Pyrenedione-Catalyzed α-Olefination of Nitriles under Visible-Light Photoredox Conditions

Bains, Amreen K.,Ankit, Yadav,Adhikari, Debashis

supporting information, p. 2019 - 2023 (2021/04/05)

Herein, we report a combination of pyrenedione (PD) and KOtBu to achieve facile alcohol dehydrogenation under visible-light excitation, where aerobic oxygen is utilized as the terminal oxidant. The resulting carbonyl compound can be easily converted to vinyl nitriles in a single-pot reaction, at 60 °C in 6-8 h. This environmentally benign, organocatalytic approach has distinct advantages over transition-metal-catalyzed α-olefination of nitriles, which often operate at a significantly higher temperature for an extended reaction time.

Synthesis and characterization of phenanthrene derivatives for optoelectronic applications

Raouafi, Sondes,Aloui, Faouzi,Raouafi, Amal,Hassine, Béchir Ben

, p. 697 - 703 (2017/06/13)

New phenanthrene derivatives, bearing cyano group at selected positions, have been prepared in good yields through Knoevenagel condensation and classical oxidative photocyclization. The optical properties of the cyanophenanthrenes have been investigated b
