741681-31-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 741681-31-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,1,6,8 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 741681-31:
(8*7)+(7*4)+(6*1)+(5*6)+(4*8)+(3*1)+(2*3)+(1*1)=162
162 % 10 = 2
So 741681-31-2 is a valid CAS Registry Number.

Emergence of a single solid chiral state from a nearly racemic amino acid derivative

Noorduin, Wim L.,Izumi, Toshiko,Millemaggi, Alessia,Leeman, Michel,Meekes, Hugo,Van Enckevort, Willem J. P.,Kellogg, Richard M.,Kaptein, Bernard,Vlieg, Elias,Blackmond, Donna G.

, p. 1158 - 1159 (2008/09/20)

The evolution of a single chiral solid state is reported for an amino acid derivative starting from a nearly racemic mixture of solid left- and right-handed crystals. Attrition-enhanced dissolution and recrystallization processes based on solubility considerations of the Gibbs-Thomson rule, coupled with solution-phase racemization, drive this near-equilibrium system inexorably to single chirality in the solid phase.
