154047-41-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 154047-41-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,0,4 and 7 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 154047-41:
(8*1)+(7*5)+(6*4)+(5*0)+(4*4)+(3*7)+(2*4)+(1*1)=113
113 % 10 = 3
So 154047-41-3 is a valid CAS Registry Number.

Ring-opening of N-tosyl aziridines by 2-lithiodithianes
Howson, William,Osborn, Helen M. I.,Sweeney, Joseph
, p. 2439 - 2446 (2007/10/02)
The reaction of lithiated dithianes 6-8 and 15 and 16 with enantiopure N-sulfonylated aziridines 1 and 2 leads via regiospecific nucleophilic ring-opening to enentiopure N-tosyl 2-(2'-dithianyl) secondary amines in good to excellent yields.These compounds
