Validation on Field : JavaScript regex required for Field

Following is the requirement of field value should be - else it should generate an error

Format to be only 9 characters with 2 letters, followed by 6 numbers, followed by one letter

Any else value should generate an error message using JavaScript. Can anyone help me in creating regex expression for this.

This will help..

/^[ ]*([a-zA-Z]{2}\d{6}[a-zA-Z])[ ]*$/

[a-zA-Z]{2} matches two alphabetic character

\d{6} matches subsequent 6 digits

[a-zA-Z] matches one alphabetic character
