210624-94-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 210624-94-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,0,6,2 and 4 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 210624-94:
(8*2)+(7*1)+(6*0)+(5*6)+(4*2)+(3*4)+(2*9)+(1*4)=95
95 % 10 = 5
So 210624-94-5 is a valid CAS Registry Number.

Br?nsted acid-catalysed conjugate addition of photochemically generated α-amino radicals to alkenylpyridines

Hepburn, Hamish B.,Melchiorre, Paolo

, p. 3520 - 3523 (2016/03/04)

The conjugate addition of α-amino radicals to alkenylpyridines has been accomplished by the synergistic merger of Br?nsted acid and visible light photoredox catalysis. Key to reaction development was the protonation of the alkenylpyridines that transientl

Electronic Interactions in Aromatic Compounds. Direct Electronic Interaction between Aromatic Rings in Conjugated and Non-Conjugated cis-Compounds

Mancini, Vittorio,Passini, Paolo,Santini, Sergio

, p. 463 - 466 (2007/10/02)

A study of charge transfer equilibria between a series of cis- and trans-4-styrylpyridines and cis- and trans-1-(4-X-phenyl)-2-(4-pyridyl)cyclopropanes with iodine has been carried out in CCl4.Acidity constants for these heteroaromatic compounds were determined.The results obtained for the two types of measurements show that through-space conjugation, due to overlap of the non-parallel ?-orbitals of the two aromatic systems, operated in both cis-systems.
