351428-89-2 Usage
Structure
An amide derivative of cyclopentadiene with five methyl groups attached to the carbon atoms in the ring
Steric hindrance
The presence of the five methyl groups makes the compound highly sterically hindered
Use in organic synthesis
Used as a building block for the construction of more complex molecules
Use as a ligand
Can bind to metal ions to form stable complexes in coordination chemistry
Potential applications
Pharmaceuticals and agrochemicals (requires further research)
Check Digit Verification of cas no
The CAS Registry Mumber 351428-89-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,1,4,2 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 351428-89:
(8*3)+(7*5)+(6*1)+(5*4)+(4*2)+(3*8)+(2*8)+(1*9)=142
142 % 10 = 2
So 351428-89-2 is a valid CAS Registry Number.

Highly Syn-?-Facial Preference in the Diels-Alder Reactions of 1,2,3,4,5-Pentamethylcyclopentadienes Having Carboxy, Ethoxycarbonyl, and Cyano Substituents at 5-Positions

Diels-Alder reactions of 1,2,3,4,5-pentamethylcyclopentadienes having carboxy, alkoxyccarbonyl, and cyano substituents at 5-positions with N-phenylmaleimide preferentially afforded the corresponding syn-attack products with the ratio of syn/anti=80 : 20 to 100 : 0, while the diene having 5-hydroxymethyl moiety gave the anti-attack product exclusively.
