Check Digit Verification of cas no
The CAS Registry Mumber 861109-20-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,1,1,0 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 861109-20:
(8*8)+(7*6)+(6*1)+(5*1)+(4*0)+(3*9)+(2*2)+(1*0)=148
148 % 10 = 8
So 861109-20-8 is a valid CAS Registry Number.

Asymmetric [2,3]-sigmatropic rearrangement of allylic ammonium ylides
Blid, Jan,Panknin, Olaf,Somfai, Peter
, p. 9352 - 9353 (2005)
An asymmetric Lewis acid-mediated [2,3]-sigmatropic rearrangement of allylic amines has been developed, affording the corresponding homoallylic amines in good yield and excellent enantioselectivities. The rearrangement proceeds by complexation of the chir
