Check Digit Verification of cas no
The CAS Registry Mumber 1111659-03-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,1,1,6,5 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1111659-03:
(9*1)+(8*1)+(7*1)+(6*1)+(5*6)+(4*5)+(3*9)+(2*0)+(1*3)=110
110 % 10 = 0
So 1111659-03-0 is a valid CAS Registry Number.

Asymmetric Lewis acid mediated [1,2]-rearrangement of proline-derived ammonium ylides
Tuzina, Pavel,Somfai, Peter
, p. 919 - 921 (2009)
The first example of asymmetric Lewis acid mediated [1,2]-rearrangement of N-benzylic proline amides to form quaternary proline derivatives is reported. The presented reaction is shown to proceed with remarkable high C→N→C chirality transfer. Various quat
