40599-78-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40599-78-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,5,9 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 40599-78:
(7*4)+(6*0)+(5*5)+(4*9)+(3*9)+(2*7)+(1*8)=138
138 % 10 = 8
So 40599-78-8 is a valid CAS Registry Number.

Models for Glycoside Hydrolysis. Synthesis and Hydrolytic Studies of the Anomers of a Conformationally Rigid Acetal

Eikeren, Paul van

, p. 4641 - 4645 (2007/10/02)

The methyl acetals of 2-hydroxy-3-oxa-trans-decalin were synthesized as models for conformationally rigid methyl glycosides.The compounds were prepared by Baeyer-Villiger oxidation of trans-hexahydrohydrindan-2-one followed by reduction of the resulting lactone with diisobutylaluminum hydride.Treatment of the hemiacetal with methanol and an acid catalyst afforded a mixture of acetals which were separated by chromatography and identified by NMR.Hydrolytic studies were carried out under a range of acid concentrations and temperatures.The mechanistic implications of the relative hydrolysis rates (axial/equatorial ratio of 1.51+/-0.22) and activation parameters are discussed.
