If you want it to be fast you can use:

internal static class Culture
{
    private static readonly HashSet CultureNames = CreateCultureNames();

    internal static bool Exists(string name)
    {
        return CultureNames.Contains(name);
    }

    private static HashSet CreateCultureNames()
    {
        var cultureInfos = CultureInfo.GetCultures(CultureTypes.AllCultures)
                                      .Where(x => !string.IsNullOrEmpty(x.Name))
                                      .ToArray();
        var allNames = new HashSet(StringComparer.OrdinalIgnoreCase);
        allNames.UnionWith(cultureInfos.Select(x => x.TwoLetterISOLanguageName));
        allNames.UnionWith(cultureInfos.Select(x => x.Name));
        return allNames;
    }
}
