905716-97-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 905716-97-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,5,7,1 and 6 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 905716-97:
(8*9)+(7*0)+(6*5)+(5*7)+(4*1)+(3*6)+(2*9)+(1*7)=184
184 % 10 = 4
So 905716-97-4 is a valid CAS Registry Number.

Amino acid-derived enaminones: A study in ring formation providing valuable asymmetric synthons
Turunen, Brandon J.,Georg, Gunda I.
, p. 8702 - 8703 (2007/10/03)
A new reaction for the preparation of enaminones has been discovered. This method employs β-amino acids as starting materials to allow diversification as well as incorporation of chirality. The β-amino acids, once converted to ynones, are readily cyclized
