Check Digit Verification of cas no

The CAS Registry Mumber 3345-11-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,4 and 5 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3345-11:
(6*3)+(5*3)+(4*4)+(3*5)+(2*1)+(1*1)=67
67 % 10 = 7
So 3345-11-7 is a valid CAS Registry Number.

Microwave-Induced Reactions of Organic Substrates in the Cage of Zeolites

Ipaktschi, Junes,Brueck, Matthias

, p. 1591 - 1593 (2007/10/02)

Microwave irradiation of compounds 1, 7, 15, 19, 23, and 24 adsorbed on Y zeolites has been studied.The reaction rate of the corresponding rearrangement, dehydrogenation and dehydration is dramatically enhanced as compared with reactions under thermal conditions.

Selective Demethylative Cyclisation of 2-Methoxy-allylbenzenes

Devakumar, C.,Mukerjee, S. K.

, p. 368 - 372 (2007/10/02)

Treatment of 3-substituted 2-methoxyallylbenzenes with dry HBr in CHCl3 causes selective demethylative cyclisation to give 7-substituted 2-methyl-2,3-dihydrobenzofurans.The reaction involves mutual participation of allyl and 2-methoxyl groups and is sterically accelerated by substituents vicinal to OCH3.The reaction does not take place in high dielectric solvents such as DMF or DMSO.A propable mechanism envisaging a non-classical ionic transition state is proposed and the synthetic utility of this reaction is also demonstrated.
