Check Digit Verification of cas no

The CAS Registry Mumber 77944-37-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,9,4 and 4 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 77944-37:
(7*7)+(6*7)+(5*9)+(4*4)+(3*4)+(2*3)+(1*7)=177
177 % 10 = 7
So 77944-37-7 is a valid CAS Registry Number.

ALKYLALUMINIUM HALIDES; LEWIS ACID CATALYSTS WHICH ARE BRONSTED BASES

Snider, Barry B.,Rodini, David J.,Karras, Michael,Kirk, Thomas C.,Deutsch, Ethan A.,et al.

, p. 3927 - 3934 (1981)

Alkylaluminium halides react with Broensted acids to liberate an alkane and generate a new Lewis acid.Using these reagents, Lewis acid catalyzed reactions can be run under aprotic conditions, even when acidic protons are produced in the reaction.The use of these reagents for Lewis acid catalyzed ene, Diels-Alder and cycloaddition reactions and Claisen rearrangements is described.These reagents are also useful initiators for cation-olefin addition reactions.In some cases the alkyl groups react as nucleophiles.While this is often undesirable, addition of an alkyl group to carbenium ion intermediates provides novel classes of compounds.

Synthesis of Allylic Sulfoxides from Alkenes by EtAlCl2-Catalyzed Ene Reaction with p-Toluenesulfinyl Chloride

Snider, Barry B.

, p. 3155 - 3156 (2007/10/02)

Ethylaluminum dichloride (EtAlCl2) catalyzes the ene reaction of alkenes with arylsulfinyl chlorides to give allylic sulfoxides since EtAlCl2 acts as a proton scavenger as well as a Lewis acid, reacting with the hydrogen chloride produced in the reaction to give aluminum trichloride and ethane.
