Check Digit Verification of cas no

The CAS Registry Mumber 313344-25-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,3,3,4 and 4 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 313344-25:
(8*3)+(7*1)+(6*3)+(5*3)+(4*4)+(3*4)+(2*2)+(1*5)=101
101 % 10 = 1
So 313344-25-1 is a valid CAS Registry Number.

Solid phase Diels-Alder/retro Diels-Alder reactions. A new method for traceless linker strategy

Blanco,Bloch,Bugnet,Deloisy

, p. 7875 - 7878 (2000)

A resin-bound furan has been efficiently synthesized from Merrifield resin. This new polymer reacts with an acetylenic dienophile to afford a thermally stable Diels-Alder adduct. Transformation of the adduct by Michael reaction with thiophenol has allowed an easy retro Diels-Alder reaction. This 'safety-catch' procedure leads to the formation of a chemically and stereochemically pure alkene and to the regeneration of the polymer-bound furan. (C) 2000 Elsevier Science Ltd.

Stereoselective 1,3-dipolar cycloaddition of a maleate derivative with azomethine ylides derived from α-amino esters: Synthesis of 3-pyrrolines

Soret, Adrien,Guillot, Régis,Rousseau, Gérard,Blanco, Luis,Deloisy, Sandrine

, p. 1284 - 1288 (2008/02/07)

A new preparation of 3-pyrrolines is described by [3+2] cycloadditions of N-metalated azomethine ylides derived from α-amino esters with a dimethyl 7-oxabicyclo[2.2.1]hepta-2,5-diene-2,3-dicarboxylate derivative, followed by retro-Diels-Alder reactions. T
