676558-59-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 676558-59-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,6,5,5 and 8 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 676558-59:
(8*6)+(7*7)+(6*6)+(5*5)+(4*5)+(3*8)+(2*5)+(1*9)=221
221 % 10 = 1
So 676558-59-1 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
