Regular Expression - Allows numbers, but not the dotted line punctuation mark

I want to write a regex. Here is my basic requirement:

• Allow only 11 numbers.
• There cannot be a dash ( -
  
  ) inside these 11 numbers.

Here is the regex I wrote:

\d{11}[^-]

      

        
        
        
      

    

Examples:
a) 12345654321 => Valid
b) 123-4567890 => Invalid
c) -1234567890 => Invalid
d) 1234567890- => Invalid

I didn't get the correct result. How do I fix this?
