108298-46-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 108298-46-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,2,9 and 8 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 108298-46:
(8*1)+(7*0)+(6*8)+(5*2)+(4*9)+(3*8)+(2*4)+(1*6)=140
140 % 10 = 0
So 108298-46-0 is a valid CAS Registry Number.

Syntheses of Highly Substituted Benzenes via Diels-Alder Reactions with 2H-Pyran-2-ones

Ziegler, Thomas,Layh, Marcus,Effenberger, Franz

, p. 1347 - 1356 (2007/10/02)

The 2H-pyran-2-ones (α-pyrones) 1 react as dienes in Diels-Alder reactions with acetylene derivatives.The primarely formed cycloadducts immediately aromatize to benzenes by CO2 elimination.Thus, methyl acetylenedicarboxylate (2a) gives dimethyl phthalates 3, and methyl acetylenediphosphonate (2b) gives dimethyl 1,2-phenylenediphosphonates 8.The reactions of 1-(dimethylamino)-1-methoxyethene (9) with 1 regioselectively produce N,N-dimethylanilines 10 and isomeric homophthalate derivatives 12.Naphthoquinones 14 could be generated from 1,4-benzoquinone (13) and 1 in the presence of acetic anhydride and Pd/C.Hydroxy-2H-pyran-2-ones 4 react via their trimethylsilyl ether 6 analogously with 2a to give dimethyl (trimethylsiloxy)phthalates 7 which are easily converted to phenols 5 by acid-catalyzed hydrolysis.
