Check Digit Verification of cas no

The CAS Registry Mumber 7575-38-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,7 and 5 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7575-38:
(6*7)+(5*5)+(4*7)+(3*5)+(2*3)+(1*8)=124
124 % 10 = 4
So 7575-38-4 is a valid CAS Registry Number.

Facile and efficient synthesis of ido-heptulosan via a strategy derived from Mo(VI)-catalysed reactions

Hricovi?niova?

, p. 751 - 754 (2001)

A simple and high-yielding method for the preparation of 2,7-anhydro-β-D-ido-heptulopyranose (IDO) is described. It utilises the ability of molybdate ions to create the conditions for the skeletal rearrangement in the molecule of 2-C-branched aldose. This evidence is used in the synthesis of IDO from 2-C-(hydroxymethyl)-2,3:5,6-di-O-isopropylidene-D-gulofuranose in one step. The title compound is obtained in 95percent yield.
