124838-73-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 124838-73-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,8,3 and 8 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 124838-73:
(8*1)+(7*2)+(6*4)+(5*8)+(4*3)+(3*8)+(2*7)+(1*3)=139
139 % 10 = 9
So 124838-73-9 is a valid CAS Registry Number.

CHIRAL COMPLEX-FORMING AGENTS AND TRANS-PHASE TRANSFER AGENTS. 5. 3S-HYDROXY-1-ALKYLQUINUCLIDINIUM SALTS AND THEIR PROPERTIES.

Esikova, I. A.,Serebryakov, E. P.

, p. 1682 - 1690 (2007/10/02)

Synthesized 3-hydroxy- and 3-benzyloxy-1-benzylquinuclidinium salts are in their catalytic activity comparable to benzyl(triethyl)ammonium chloride and are inferior to catalysts of the tetraalkylammonium type.The asymmetry-induced capability of chiral 3-hydroxy-1-alkylquinuclidinium salts is considerably inferior to the asymmetry-induced capability of the conformationally mobile N-benzylquininium chloride, which indicates the dependence of the asymmetric induction on the possibility of the approach of the β-hydroxylic group and the ammonium center of the catalyst in the transition state of the reaction.
