144782-49-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144782-49-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,7,8 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 144782-49:
(8*1)+(7*4)+(6*4)+(5*7)+(4*8)+(3*2)+(2*4)+(1*9)=150
150 % 10 = 0
So 144782-49-0 is a valid CAS Registry Number.

Synthesis and stereoselective reductions of chiral β-iminosulfoxides
Garcia Ruano,Lorente,Rodriguez
, p. 5637 - 5640 (1992)
Reaction of chiral non racemic β-ketosulfoxides with amines or condensation of the imine enolates with (-)-menthyl sulfinate yield optically pure β-iminosulfoxides. The second method requires the presence of an excess of MgBr2 in order to avoid
