Calculate Digit Verification of CAS Registry Number 81668-67:
(7*8)+(6*1)+(5*6)+(4*6)+(3*8)+(2*6)+(1*7)=159
159 % 10 = 9
So 81668-67-9 is a valid CAS Registry Number.

α-C-Glycopyranosides from Lewis Acid Catalysed Condensations of Acetylated Glycals and Enol Silanes

Dawe, Robert David,Fraser-Reid, Bert

, p. 1180 - 1181 (1981)

Acetylated glycals undergo Lewis acid-catalysed condensations with enol silanes in virtually quantitative yields to form C-glycopyranosides in which the thermodynamically unfavourable α-'anomers' are formed predominantly.
