60582-30-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 60582-30-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,5,8 and 2 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 60582-30:
(7*6)+(6*0)+(5*5)+(4*8)+(3*2)+(2*3)+(1*0)=111
111 % 10 = 1
So 60582-30-1 is a valid CAS Registry Number.

Selective synthesis of 4,6-O-alkenylidene and -benzylidene acetals from unprotected sucrose by lanthanide(III) resin-catalyzed transacetalization

Porwanski,Salanski,Descotes,Bouchu,Queneau

, p. 525 - 528 (2007/10/03)

Lanthanide cation exchanged resins were used as catalysts for the acetalization of sucrose. Ytterbium(III)- and erbium(III)-exchanged resins promote the transacetalization of dialkyl acetals of α,β-unsaturated aldehydes. A two-step one-pot procedure provides direct access from the unsaturated aldehyde to a series of sucrose 4,6-acetals in good yields from unprotected sucrose without concomitant glycosidic bond cleavage.

Acetal Formation Facilitated in 2-Hydroxyaryl Aldehydes by Intramoleculedar Acyl Group Transfer

Liepa, Andris J.,Morton, Trevor C.

, p. 1747 - 1757 (2007/10/02)

Convenient preparations of synthetically useful acetals, a dithioacetal and an oxathiolan from the 2-acyl derivatives of 2-hydroxyaryl aldehydes under basic conditions are described.The mildness of the reaction conditions is illustrated by the formation of an ethoxycarbonyl-substituted dioxolan.The reaction is dependent upon an intramolecular acetyl group transfer and the mechanism of the reaction is discussed.Some broader implications of this type of acyl transfer are discussed.
