127924-49-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127924-49-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,9,2 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 127924-49:
(8*1)+(7*2)+(6*7)+(5*9)+(4*2)+(3*4)+(2*4)+(1*9)=146
146 % 10 = 6
So 127924-49-6 is a valid CAS Registry Number.

STEREOSELECTIVE SYNTHESIS OF "LINEAR" C-DISACCHARIDES
Daly, Sharon M.,Armstrong, Robert W.
, p. 5713 - 5716 (2007/10/02)
A 1,4'-C-disaccharide (20) containing an acetylenic linkage was synthesized from D-glucose via a homologation of a 4-ulose derivative (6a) followed by condensation with 2,3,4,6-tetrabenzyl pyranolactone.Subsequent reduction afforded isomerically pure β-C-disaccharide in good overall yield.
