You can divide a four-digit number into two two-digit numbers and combining them using hundred, and it is common for numbers 1100 through 1999. You cannot divide a number if it is a multiple of 1000. The number 2000 is always read "two thousand," never "twenty hundred."

The number 1976 is read as follows:

one		thousand		nine		hundred		seventy	-	six
1	×	1000	+	9	×	100	+	(7 × 10^†	+	6)

nineteen		hundred		seventy	-	six
(9 + 10^*)	×	100	+	(7 × 10^†	+	6)

There are poetic number names for multiples of twenty.
