No.

Rectifiers must be should be rated no less than TWICE input voltage for such
a multiplier. Take a look at the first stage. One cycle charges the first
cap though the first diode. Then the AC voltage reverses, and there is now
peak lin voltage + charged capacitor voltage across that first diode. This
process repeats for each stage you have. Multipliers work by "adding" line
voltage to each previously charged stage of capacitors. As each stage has
charged, the additional voltage from the input then goes to charge the next
cap.
