Check Digit Verification of cas no
The CAS Registry Mumber 38838-08-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,8,3 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 38838-08:
(7*3)+(6*8)+(5*8)+(4*3)+(3*8)+(2*0)+(1*8)=153
153 % 10 = 3
So 38838-08-3 is a valid CAS Registry Number.

Synthesis of 6-amino-6-deoxy-2,3,4,5-tetra-O-methyl-D-galactonic acid, a key precursor of a stereoregular polyamide
Romero Zaliz, Carmen L.,Varela, Oscar
, p. 689 - 701 (2001)
The title compound (17) was synthesized by two alternative sequences, starting from D-galactose diacetonide (1) and from methyl 6-O-tosyl-α-D-galac-topyranoside (9). Compound 1 was converted into the 6-bromo-6-deoxy derivative 2 or mesylated to 3. Nucleop
Conversion of alcohols to bromides using a fluorous phosphine
Desmaris, Laurence,Percina, Nathalie,Cottier, Louis,Sinou, Denis
, p. 7589 - 7591 (2007/10/03)
Reaction of alcohols with the fluorous phosphine-carbon tetrabromide complex in toluene or in a two-phase toluene-FC-72 system afforded the corresponding bromides in good yields. The fluorous-phosphine oxide is readily separated by liquid-liquid extraction, providing an alternative to the homogeneous triphenylphosphine-carbon tetrachloride conversion, as well as to the polymer-supported phosphine method. The fluorous phosphine oxide could be reduced and the product reused.
A new approach to some 1,6-dideoxy 1,6-epithio sugars
Driguez, Hugues,McAuliffe, Joseph C.,Stick, Robert V.,Tilbrook, Matthew G.,Williams, Spencer J.
, p. 343 - 348 (2007/10/03)
The treatment of hexopyranosyl bromides, also activated at C6 (Br, OTs, OMs), with H2S/HCONMe2 under basic conditions gives rise to 1,6-dideoxy 1,6-epithio sugars. One such sugar has been further transformed into the synthetically useful 3,4-anhydro-1,6-dideoxy-1,6-epithio-β-D-galactose. The treatment of this epoxide with sodium azide and with cyclohexylamine is described. An analogous treatment of one doubly activated hexopyranosyl bromide with sodium hydrogen selenide has led to a novel 1,6-dideoxy 1,6-episeleno sugar which displayed interesting n.m.r. spectra. Finally, in an attempt to prepare 1,6-dideoxy 1,6-epidithio sugars, a tetraalkylammonium tetrathiomolybdate reagent was found to be the reagent of choice for converting doubly activated hexopyranosyl bromides into 1,6-dideoxy 1,6-epithio sugars.
