SELECT with WHERE clause on alphanumeric values

I have a table that has an column id of the form D1,D2,D3...

I want to select the rows based on:

SELECT * FROM "SAP_ECC"."PARSONSF"."VBRP"

WHERE "VBELN" >= 'D10' AND "VBELN" <= 'D100'

to retrieve D1,D2,D3,D4...D100

But I only get D1,D10,D100.

Any ideas how I can do this?

Thank you!
