6542-00-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6542-00-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,4 and 2 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6542-00:
(6*6)+(5*5)+(4*4)+(3*2)+(2*0)+(1*0)=83
83 % 10 = 3
So 6542-00-3 is a valid CAS Registry Number.

Stereochemistry of the tetrabutylammonium cyanide-catalyzed cyanosylilation of cyclic α,β-epoxyketones - Dependence of the diastereoselectivity on the ring size

Aljarilla, Ana,Cordoba, Ruben,Csaky, Aurelio G.,Fernandez, Israel,Ortiz, Fernando Lopez,Plumet, Joaquin,Gomez, Gloria Ruiz

, p. 3969 - 3976 (2007/10/03)

The diastereoselective Bu4NCN-catalyzed addition of TMSCN to cyclic α,β-epoxyketones has been considered. Good diastereoselectivities were found, depending on the ring size of the starting material. Computational studies account for the observed diastereoselectivities. Wiley-VCH Verlag GmbH & Co. KGaA, 2006.

Total synthesis of coriandrin and 7-demethylcoriandrin via a new synthesis of isocoumarins

Mal, Dipakranjan,Bandyopadhyay, Mousumi,Ghorai, Sujit K.,Datta, Kalyani

, p. 3677 - 3680 (2007/10/03)

Indenone epoxides 8, prepared from the corresponding indenones, have been shown to undergo clean thermal rearrangement to give isocoumarins 10 in high yields. This synthesis of isocoumarins, when applied to oxaindace-none 7, resulted in the total synthesis of coriandrin (1). (C) 2000 Elsevier Science Ltd.
