263752-03-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 263752-03-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,3,7,5 and 2 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 263752-03:
(8*2)+(7*6)+(6*3)+(5*7)+(4*5)+(3*2)+(2*0)+(1*3)=140
140 % 10 = 0
So 263752-03-0 is a valid CAS Registry Number.

Asymmetric cyclopropanation catalyzed by C2-symmetric bi(oxazolines)
Boulch, Rachel,Scheurer, Andreas,Mosset, Paul,Saalfrank, Rolf W.
, p. 1023 - 1026 (2007/10/03)
C2-symmetric bi(oxazolines) 3a-e were prepared in three steps based on a tartaric-derived vicinal diamine as common precursor. These chiral ligands were studied with respect to their directive influence on the enantioselective copper catalyzed
