Check Digit Verification of cas no

The CAS Registry Mumber 238757-43-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,8,7,5 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 238757-43:
(8*2)+(7*3)+(6*8)+(5*7)+(4*5)+(3*7)+(2*4)+(1*3)=172
172 % 10 = 2
So 238757-43-2 is a valid CAS Registry Number.

Synthesis of enantiopure C-glycosides and pseudo C-glycosides. Lewis acid mediated cleavage of [3.3.1] oxabicyclic lactones

Gaertzen, Oliver,Misske, Andrea M.,Wolbers, Peter,Hoffmann

, p. 1041 - 1044 (1999)

Lewis acid mediated cleavage of substituted 2,9-dioxabicyclo[3.3.1]nonan-3-ones affords enantiopure 2,6-trans-C-glycosides in excellent yield. Variation of nucleophile, solvent and Lewis acid were investigated.
