32119-56-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 32119-56-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,1,1 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 32119-56:
(7*3)+(6*2)+(5*1)+(4*1)+(3*9)+(2*5)+(1*6)=85
85 % 10 = 5
So 32119-56-5 is a valid CAS Registry Number.

A photoredox catalyzed radical-radical coupling reaction: Facile access to multi-substituted nitrogen heterocycles

Li, Weipeng,Duan, Yingqian,Zhang, Muliang,Cheng, Jian,Zhu, Chengjian

supporting information, p. 7596 - 7599 (2016/07/06)

Visible light induced photoredox catalysis is an efficient method for radical activation. Herein, we report the photoredox catalysis involving an intramolecular radical-radical coupling reaction that proceeds through a biradical intermediate. This protocol represents a new synthetic route to construct multi-substituted N-heterocycles. Four, five and six-membered N-heterocyclic structures with a quaternary carbon center are accessible under mild conditions.
