Check Digit Verification of cas no
The CAS Registry Mumber 100784-84-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,7,8 and 4 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 100784-84:
(8*1)+(7*0)+(6*0)+(5*7)+(4*8)+(3*4)+(2*8)+(1*4)=107
107 % 10 = 7
So 100784-84-7 is a valid CAS Registry Number.

The Synthesis and Chemistry of Azolenines. Part 4. Preparation and Rearrangement of some 3,5-Diaryl-2H-pyrrole-2,2-dicarboxylic Esters

Oxidation of diethyl 3,5-diaryl-3,4-dihydro-2H-pyrrole-2,2-dicarboxylates (3) with chloranil in refluxing xylene gives not the 3,5-diaryl-2H-pyrrole-2,2-dicarboxylates (4) as reported by an earlier group, but instead the rearranged, isomeric, 1H-pyrrole-1,2-dicarboxylates (5). 2H-Pyrroles (4) may be obtained from the dihydropyrroles (3) using DDQ in benzene at room temperature; they rearrange to the isomers (5) in boiling xylene via an acyl -sigmatropic shift from carbon to nitrogen, a novel process in the 2H-pyrrole series.Thermal analyses indicate that the rearrangement is concerted with negligible charge separation in the transition state.Other novel 3,5-diaryl-1H-pyrrole-2-carboxylic acid derivatives are described.
