Split on commas and find the is in the resulting array:

function has_is(str) {
  return str.split(/,\s*/) . indexOf('is') !== -1;
}

has_is("is, a, line") // true
has_is("this, is, a, line") // true
has_is("this, is") // true
has_is("this, is a, line") //false

Make sure that the sub-string is preceeded by start or the line boundary or comma and followed by end of the line boundary or comma with zero or more spaces in-between. 

string.match(/(?:^|,)\s*is\s*(?:,|$)/)
