289894-50-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 289894-50-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,8,9 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 289894-50:
(8*2)+(7*8)+(6*9)+(5*8)+(4*9)+(3*4)+(2*5)+(1*0)=224
224 % 10 = 4
So 289894-50-4 is a valid CAS Registry Number.

Enantioselective Molecular Recognition between β-Sheets

Chung, De Michael,Nowick, James S.

, p. 3062 - 3063 (2004)

This communication asks whether homochiral or heterochiral interaction is preferred between enantiomeric β-sheets and finds that homochiral pairing is strongly preferred. Interactions between β-sheets occur widely among proteins through pairing of the hyd

Mesomorphic properties of 1-(4'-dodecylbiphenyl-4-yl)-3-(2 or 3-alkoxyphenyl)propane-1,3-diones: the influence of alkoxysubstituent position

Sadashiva, Bukkinakere K.,Prasad, Veena

, p. 755 - 760 (2007/10/03)

Two homologous series of β-diketones, viz. 1-(4'-dodecylbiphenyl-4-yl)-3-(2-alkoxyphenyl)propane-1,3-diones and 1-(4'-dodecylbiphenyl-4-yl)-3-(3-alkoxyphenyl)propane-1,3-diones have been synthesised.The mesomorphic behaviour of all the compounds has been investigated using optical polarising microscopy and differential scanning colorimetry.The enthalpies associated with the transitions of all the liquid crystalline materials have also been determined.The mesophases exhibited by these compounds are explained on the basis of the structural features associated with such compounds.
