Check Digit Verification of cas no

The CAS Registry Mumber 173094-49-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,0,9 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 173094-49:
(8*1)+(7*7)+(6*3)+(5*0)+(4*9)+(3*4)+(2*4)+(1*9)=140
140 % 10 = 0
So 173094-49-0 is a valid CAS Registry Number.

Synthese d'oxazolines insaturees isomeres a partir d'aminoalcools chiraux en vue du greffage sur silice

Leveque, Hubert,Malhiac, Catherine,Speybrouck, David,Combret, Yvette,Guerpin, Valerie,Combret, Jean-Claude

, p. 801 - 807 (2007/10/02)

Synthesis of unsaturated oxazoline isomers from chiral amino alcohols for bonding to silica.In order to study their enantioselective ability, four chiral unsaturated oxazoline isomers were synthesized from (1S,2S)-2-amino-1-phenylpropane-1,3-diol and (2S,3R)-2-amino-3-hydroxybutanoic acid (S-threonine).A terminal double bond was introduced on these structures in order to be able to graft them onto silica and access chiral stationary phases for chromatography. - Keywords: chiral unsaturated oxazoline; heterocyclization; selective reaction; grafted silica
