201424-73-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 201424-73-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,4,2 and 4 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 201424-73:
(8*2)+(7*0)+(6*1)+(5*4)+(4*2)+(3*4)+(2*7)+(1*3)=79
79 % 10 = 9
So 201424-73-9 is a valid CAS Registry Number.

New homochiral bis(oxazoline) ligands for asymmetric catalysis
Hoarau,Ait-Haddou,Castro,Balavoine
, p. 3755 - 3764 (2007/10/03)
Several homochiral bis(oxazolines), with asymmetric centers on the oxazoline rings and on the side chains, were prepared from (1S,2S)-(+)-2-amino-1-phenyl-1,3-propanediol in high yields. Asymmetric cyclopropanation of styrene with ethyl diazoacetate in th
