I couldn't find a description of the algorithm anywhere but since the
web page cited does it all in Javascript I figured it couldn't be too
hard to decipher. 100+ lines of Javascript came down to this:

function ESNHexToDecimalString(Value: string) : String;

function Convert(HexString : string; Len : integer) : String;
begin
if trim(HexString) = '' then Result := '0' else
Result := IntToStr(StrToInt('$' + trim(HexString)));
while length(Result) < Len do Result := '0' + Result;
end;

begin
Result := Convert(copy(Value, 1, 2), 3) +
Convert(copy(Value, 3, Length(Value)), 8);
end;
