7191-90-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7191-90-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,9 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7191-90:
(6*7)+(5*1)+(4*9)+(3*1)+(2*9)+(1*0)=104
104 % 10 = 4
So 7191-90-4 is a valid CAS Registry Number.

The curious case of salicylidene-based fluoride sensors: Chemosensors or chemodosimeters or none of them

Dey, Sandeep Kumar,Janiak, Christoph

, p. 14689 - 14693 (2020)

Fluoride-ion induced hydrolysis of imine (CN) bonds has not been documented in the literature, in spite of the numerous salicylidene-based fluoride sensors studied over the years. Herein, we have proposed a mechanism for fluoride-ion induced hydrolysis of salicylidene compounds (SL and CL1-3) based on 1H-NMR, 19F-NMR, LC-MS and UV-vis spectroscopy experiments.

Reactions of pyridoxal with aromatic diamines

Bagautdinova, Roza Kh.,Kibardina, Lyudmila K.,Burilov, Alexander R.,Strelnik, Anna G.,Pudovik, Mikhail A.

, p. 326 - 330 (2020/05/04)

[Figure not available: see fulltext.] Pyridoxal monoimines were obtained by the reaction of pyridoxal with aromatic diamines. A change in the ratio of the reagents or introduction of another aromatic aldehyde into the reaction leads to the formation of sy

Three-Way Chemoselectivity Switching through Coupled Equilibria

Puangsamlee, Thamon,Miljani?, Ognjen ?.

supporting information, p. 5900 - 5904 (2020/08/05)

Controlling the chemoselectivity of reactions operating on complex mixtures, including those found in biological and petrochemical feedstocks or in the primordial soup from which life emerged, is generally challenging. The selectivity of imine oxidation c
