The regular expression would be: (i|I)\d{5}\.\d (i|I) -> either a lower case or an upper case i \d{5} -> five sequential digits \. -> the decimal point \d - one digit so the fully escaped regex on .net would be var exp = new RegExp("(i|I)\\d{5}\\.\\d"); Note: you could also use the ignore case Regex option flag and just include the i instead of (i|I) P.S. I would recommend use of the Regex Coach - a nifty little tool for designing and testing regular expressions: http://www.weitz.de/regex-coach/[^]
