Check Digit Verification of cas no

The CAS Registry Mumber 56454-22-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,4,5 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 56454-22:
(7*5)+(6*6)+(5*4)+(4*5)+(3*4)+(2*2)+(1*2)=129
129 % 10 = 9
So 56454-22-9 is a valid CAS Registry Number.

LEWIS ACID CATALYZED HALOGENATION OF ACTIVATED CARBON ATOMS

-

Page/Page column 26, (2008/06/13)

A practical and efficient method for halogenation of activated carbon atoms using readily available /V-haloimides and a Lewis acid catalyst has been disclosed. This methodology is applicable to a range of compounds and any halogen atom can be directly introduced to the substrate. The mild reaction conditions, easy workup procedure and simple operation make this method valuable from both an environmental and preparative point of view.

Lewis acid catalyzed highly selective halogenation of aromatic compounds

, p. 2837 - 2842 (2007/10/03)

A simple and efficient procedure for the halogenation of aromatic compounds with NCS, NBS, NIS and NFSI in the presence of catalytic amount of ZrCl 4 is described. Chlorination, bromination, iodination and fluorination of various aromatic compounds are performed with high selectivity under mild reaction conditions. Georg Thieme Verlag Stuttgart.

Chlorination of Pyrrole. N-Chloropyrrole: Formation and Rearrangement to 2- and 3-Chloropyrrole

Rosa, Michael De

, p. 1008 - 1010 (2007/10/02)

N-Chloropyrrole (2) was formed in 65-72percent yield when pyrrole (1) in CCl4 was chlorinated with aqueous NaOCl.This intermediate rearranged in methanol to give chloropyrroles by two distinct reactions: a thermal rearrangement which gave 2-chloropyrrole (3) and an acid-catalyzed intermolecular reaction which gave 2-chloropyrrole (3), 3-chloropyrrole (4), and 2,5-dichloropyrrole (5).Nucleophilic attack on the N-Cl bond of 2 was demonstrated by reactions in the presence of CN- and SCN-.In the latter case, 2-(thiocyano)pyrrole was formed.

Acid Catalyzed Chlorination of Pyrrole With N-Chloroacetanilide

Rosa, Michael De

, p. 1585 (2007/10/02)

The chlorination of pyrrole with N-chloroacetanilide was catalyzed by acetic acid.Transfer of Cl+ occurred directly to the α and β positions of pyrrole and a mixture of 2-chloro-, 3-chloro- and 2,5-dichloropyrrole was formed.The α/β ratio was 10:1 under competitive conditions.
