Check Digit Verification of cas no

The CAS Registry Mumber 58996-26-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,9,9 and 6 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 58996-26:
(7*5)+(6*8)+(5*9)+(4*9)+(3*6)+(2*2)+(1*6)=192
192 % 10 = 2
So 58996-26-2 is a valid CAS Registry Number.

Mechanochemical Friedel-crafts acylations

Dud, Mateja,Bri?, Anamarija,Ju?inski, Iva,Gracin, Davor,Margeti?, Davor

, p. 1313 - 1320 (2019)

Friedel-Crafts (FC) acylation reactions were exploited in the preparation of ketone-functionalized aromatics. Environmentally more friendly, solvent-free mechanochemical reaction conditions of this industrially important reaction were developed. Reaction parameters such as FC catalyst, time, ratio of reagents and milling support were studied to establish the optimal reaction conditions. The scope of the reaction was explored by employment of different aromatic hydrocarbons in conjunction with anhydrides and acylation reagents. It was shown that certain FC-reactive aromatics could be effectively functionalized by FC acylations carried out under ball-milling conditions without the presence of a solvent. The reaction mechanism was studied by in situ Raman and ex situ IR spectroscopy.
