134643-01-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 134643-01-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,6,4 and 3 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 134643-01:
(8*1)+(7*3)+(6*4)+(5*6)+(4*4)+(3*3)+(2*0)+(1*1)=109
109 % 10 = 9
So 134643-01-9 is a valid CAS Registry Number.

Synthesis of C2 symmetric 2,2′-bipyridyl imidazolidinone and oxazaborolidine derivatives

Ward, Robert S.,Branciard, Denis,Dignan, Rosemary A.,Pritchard, Martyn C.

, p. 157 - 170 (2007/10/03)

4,4′-Bis(bromomethyl)-2,2′-bipyridine reacts with (4R, 5R)-1-propanoyl-4,5-diphenylimidazolidinone to form a C2 symmetric chiral bipyridine derivative. Similarly reaction of 4,4′-bis(bromomethyl)-2,2′-bipyridine with an amino alcohol prepared from L-tyrosine affords a C2 symmetric diaminodiol. Treatment of the latter product with either borane or trimethylboroxine forms oxazaborolidines that have been used as catalysts in the asymmetric reduction of acetophenone. High enantiomeric excesses are obtained.

, p. 1425 - 1427 (2007/10/02)

The aldol reaction of the boron enolate bearing the titled chiral auxiliary proceeded with high face selectivity.
