Check Digit Verification of cas no

The CAS Registry Mumber 188192-03-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,1,9 and 2 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 188192-03:
(8*1)+(7*8)+(6*8)+(5*1)+(4*9)+(3*2)+(2*0)+(1*3)=162
162 % 10 = 2
So 188192-03-2 is a valid CAS Registry Number.

Easy access to C-glycosides from aldonolactones by a Claisen-type chain-extension reaction

Csuk, Rene,Kuehn, Martin,Stroehl, Dieter

, p. 1311 - 1322 (1997)

Chain elongated 2,4-diuloses 2, 4, 6, 9-11, 24, 25 were conveniently obtained from the corresponding aldonolactones 1, 3, 5 by their reaction with carbonyl compounds in the presence of sodium hydride. These hemiacetalic products can be transformed into C-
