889888-75-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 889888-75-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,9,8,8 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 889888-75:
(8*8)+(7*8)+(6*9)+(5*8)+(4*8)+(3*8)+(2*7)+(1*5)=289
289 % 10 = 9
So 889888-75-9 is a valid CAS Registry Number.

Asymmetric synthesis of chiral bisoxazolines and their use as ligands in metal catalysis
Atodiresei, Iuliana,Schiffers, Ingo,Bolm, Carsten
, p. 620 - 633 (2007/10/03)
Novel C2- and C1-symmetric chiral bisoxazolines with a cyclic backbone have been synthesized in an asymmetric manner starting from meso anhydrides. All synthetic steps are easy to perform and lead to the desired products in good over
