You can use this regular expression:

\d{6}\.\d{4}

For example:

/\d{6}\.\d{4}/.test("123456.1234");
=> true
/\d{6}\.\d{4}/.test("1234.123456");
=> false

Try the below regex,

^[0-9]{6}\.[0-9]{4}$

You need to specify the start ^ and the end$.

Use this:

if (/^\d{4}\.\d{6}$/m.test(yourString)) {
    // It matches!
} else {
    // Nah, no match...
}
