165104-81-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 165104-81-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,5,1,0 and 4 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 165104-81:
(8*1)+(7*6)+(6*5)+(5*1)+(4*0)+(3*4)+(2*8)+(1*1)=114
114 % 10 = 4
So 165104-81-4 is a valid CAS Registry Number.

The use of nonactivated iminodienophiles in the stereoselective aza-Diels-Alder reaction
Trifonova, Anna,Andersson, Pher G.
, p. 445 - 452 (2007/10/03)
This paper describes the preparation of nitrogen-containing bicycles by the aza-Diels-Alder reaction of nonactivated iminodienophiles and cyclopentadiene. Readily available starting materials such as (S)-(-)-lactate and L-amino acids were used for the pre
