A duoquinquagintillion is equal to 10159 in America, or 10312 in France and Germany by Conway-Wechsler system.[1][2][3][4][5]
In the long scale which is commonly used in France and Germany, 10159 is called sesvigintilliard.
Sbiis Saibian says that Jonathan Bowers coined doequinquagintillion for this number.[6]
