Check Digit Verification of cas no

The CAS Registry Mumber 81028-14-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,0,2 and 8 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 81028-14:
(7*8)+(6*1)+(5*0)+(4*2)+(3*8)+(2*1)+(1*4)=100
100 % 10 = 0
So 81028-14-0 is a valid CAS Registry Number.

Stereocontrolled construction of tetrasubstituted tetrahydrofurans: Synthesis of 2,5-anhydro d-glucitol

Das, Biswanath,Kumar, Duddukuri Nandan

scheme or table, p. 6011 - 6013 (2010/11/21)

A highly stereoselective construction of 2,3,4,5-tetrasubstituted tetrahydrofurans has been accomplished by an unusual intramolecular 5-endo-tet cyclization of 2,3-epoxy alcohols involving hydroxyl nucleophile. The method has been utilized for the synthes

Synthesis of Saccharides and Related Polyhydroxylated Natural Products. 1. Simple Alditols

Katsuki, T.,Lee, A. W. M.,Ma, P.,Martin, V. S.,Masamune, S.,et al.

, p. 1373 - 1378 (2007/10/02)

A new approach to sugar synthesis is demonstrated through syntheses of tetritols, pentitols, and hexitols; titanium-catalyzed asymmetric epoxidation and a new selective opening reaction of 2,3-epoxy alcohols play essential roles.
