35487-33-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 35487-33-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,4,8 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 35487-33:
(7*3)+(6*5)+(5*4)+(4*8)+(3*7)+(2*3)+(1*3)=133
133 % 10 = 3
So 35487-33-3 is a valid CAS Registry Number.

Rapid preparation of 3-deoxyanthocyanidins and novel dicationic derivatives: New insight into an old procedure

Chassaing, Stefan,Kueny-Stotz, Marie,Isorez, Geraldine,Brouillard, Raymond

, p. 2438 - 2448 (2008/03/13)

Common 3-deoxyanthocyanidins and original dicationic flavylium- benzopyrylium derivatives are easily and efficiently synthesized through reactions between the corresponding phenols and aryl ethynyl ketones in the presence of aqueous hexafluorophosphoric acid. The mechanism of the reaction is discussed and two competitive pathways are consistent with our results. Wiley-VCH Verlag GmbH & Co. KGaA, 2007.

Nucleophilic addition to aryl ethynyl ketone: Addition of oxygen containing nucleophiles to terephthaloyl acetylene

Tiwari,Saxena,Venkataramani

, p. 1263 - 1266 (2007/10/03)

Base-catalysed addition of phenols to terephthaloylacetylene yields trans-1, 4-bis(3-aryloxy-2-propenoyl)benzenes 10-16 only. However, under identical conditions alcohols do not give the addition products; only polycyclotrimerisation of terephthaloylacety
