171898-68-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 171898-68-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,1,8,9 and 8 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 171898-68:
(8*1)+(7*7)+(6*1)+(5*8)+(4*9)+(3*8)+(2*6)+(1*8)=183
183 % 10 = 3
So 171898-68-3 is a valid CAS Registry Number.

A convenient method for the aromatic amino-claisen rearrangement of N-(1,1-disubstituted-allyl)anilines
Cooper,Lucas,Taylor,Ward,Williamson
, p. 621 - 625 (2007/10/03)
N-(1,1-Disubstituted-allyl)anilines are rearranged cleanly and in high yield to 2-(3,3-disubstituted-allyl)anilines using a catalytic amount of p-toluenesulfonic acid in acetonitrile/water (10:1).
