Calculate Digit Verification of CAS Registry Number 945657-30:
(8*9)+(7*4)+(6*5)+(5*6)+(4*5)+(3*7)+(2*3)+(1*0)=207
207 % 10 = 7
So 945657-30-7 is a valid CAS Registry Number.

Facile synthesis of 4-functionalized cyclopentenones

Ghorai, Sujit Kumar,Hazra, Nirmal Kumar,Mal, Dipakranjan

, p. 1949 - 1956 (2007)

1-8-Diazabicyclo[5.4.0]undec-7-ene(DBU)-catalyzed Michael addition of nitroalkanes to dicyclopentadienone (1) followed by flash vacuum pyrolysis (FVP) provided a high-yielding synthesis of extremely pure 4-nitroalkyl cyclopentenones (3). The optimized Nef reaction of the nitro adducts (2) provided 4-ketoalkyl cyclopentenones (5) in the similar way. Copyright Taylor & Francis Group, LLC.
