50705-54-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 50705-54-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,7,0 and 5 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 50705-54:
(7*5)+(6*0)+(5*7)+(4*0)+(3*5)+(2*5)+(1*4)=99
99 % 10 = 9
So 50705-54-9 is a valid CAS Registry Number.

HPLC analysis of the product distrtoution in the iodine-catalyzed methyl glycosidation of pentoses and 6-deoxyhexoses

Gyemant, Gyoengyi,Liptak, Andras

, p. 359 - 368 (2007/10/03)

The product distribution of the iodine-catalyzed methyl glycosidation of four pentoses (D-ribose, D-arabinose, D-xylose, and D-lyxose) and two 6-deoxyhexoses (L-rhamnose, and D-fucose) was studied by HPLC using an APS column (dihydrogen sulphate form) with different acetonitrile-water mobile phases. In agreement with earlier results, a temperature dependent on-column isomerization was observed for all the investigated aid oses, except for ribose. The first-eluted furanosides were followed by pyranosides, and the free sugars were eluted last with the highest retention volumes.
