Check Digit Verification of cas no

The CAS Registry Mumber 850449-41-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,0,4,4 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 850449-41:
(8*8)+(7*5)+(6*0)+(5*4)+(4*4)+(3*9)+(2*4)+(1*1)=171
171 % 10 = 1
So 850449-41-1 is a valid CAS Registry Number.

Asymmetric alkynyl additions to aldehydes catalyzed by tunable oxovanadium(V) complexes of Schiff bases of β-amino alcohols

Hsieh, Sheng-Hsiang,Gau, Han-Mou

, p. 1871 - 1874 (2006)

The first example of asymmetric alkynyl additions to aldehydes catalyzed by oxovanadium(V) catalysts of tridentate Schiff bases of β-amino alcohols 3a-h is reported. Catalytic reactions employing the best-performing catalyst 3g furnish chiral propargyl alcohols in good to excellent enantioselectivities from 73% to 99% ee. Georg Thieme Verlag Stuttgart.

Substituent effects and mechanism elucidation of enantioselective sulfoxidation catalyzed by vanadium Schiff base complexes

Zeng, Qingle,Wang, Heqing,Weng, Wen,Lin, Wenshi,Gao, Yuxing,Huang, Xiantong,Zhao, Yufen

, p. 1125 - 1127 (2007/10/03)

The effects of substituents of the Schiff base ligands on oxovanadium-catalyzed enantioselective sulfoxidation were first systematically studied, and a rational mechanism of enantioselective sulfoxidation based on our experimental data and the reported da

A highly enantioselective Strecker reaction catalyzed by titanium-N-salicyl-β-aminoalcohol complexes

Banphavichit, Vorawit,Mansawat, Woraluk,Bhanthumnavin, Worawan,Vilaivan, Tirayut

, p. 10559 - 10568 (2007/10/03)

N-salicyl-β-amino alcohols 1 were synthesized and evaluated as ligands for catalytic asymmetric Strecker reactions. N-Benzhydrylaldimines derived from aromatic and aliphatic aldehydes reacted with TMSCN in the presence of 10 mol% of Ti-1 complex to give t
