Check Digit Verification of cas no

The CAS Registry Mumber 128775-70-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,7,7 and 5 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 128775-70:
(8*1)+(7*2)+(6*8)+(5*7)+(4*7)+(3*5)+(2*7)+(1*0)=162
162 % 10 = 2
So 128775-70-2 is a valid CAS Registry Number.

STEREOSELECTIVE C-C BOND FORMATION IN CARBOHYDRATES BY RADICAL CYCLIZATION REACTIONS -- III. STRATEGY FOR THE PREPARATION OF C(1)-GLYCOSIDES.

Mesmaeker, Alain De,Hoffmann, Pascale,Ernst, Beat,Hug, Paul,Winkler, Tammo

, p. 6307 - 6310 (2007/10/02)

A new strategy for the stereoselective synthesis of α- and β-C(1)-glycosides based on an intramolecular radical cyclization reaction is described.Intramolecular hydrogen atom transfer was observed depending on the concentration of the reagents, the conformation and the substitution of the cyclized radical.
