You cannot. Although infinity was understood by the Ancient Romans (from the Latin infinitas), they had no symbol to denote it. CIƆ was the original symbol for 1,000, but was sometimes used to just mean "many", which isn't the same as saying infinity.
John Wallis introduced the infinity symbol, ∞, in 1655, by which time the Hindu-Arabic numeral system had replaced the Roman numeral system. However, it is thought he may have derived the symbol from CIƆ, which was also written as ↀ (hence the influence on D, for 500). However it's just as likely he derived it from the Greek letter ω (omega).
