How to add Multiple Regular Expression Validation attribute into one Property in ASP.Net MVC?

Create another new attribute and inherit from RegularExpressionAttribute

    public class RegularExpressionAttribute : ValidationAttribute
    {
        private string _pattern;
        public RegularExpressionAttribute(string pattern)
        {
            _pattern = pattern;
        }
        protected override ValidationResult IsValid(object value, ValidationContext validationContext)
        {
            if (value == null) return null;
            if (!System.Text.RegularExpressions.Regex.IsMatch(value.ToString(), _pattern))
            {
                return new ValidationResult(FormatErrorMessage(validationContext.DisplayName));
            }
            return null;
        }

    public class RegularExpression2ndAttribute : RegularExpressionAttribute {}


So in view model:
        [ValidURL(ErrorMessage = "Invalid URL")]
        [RegularExpression(@"^.*\.(jpg|JPG|gif|GIF|jpeg)$", ErrorMessage = "Not a image URL")]
        public string LogoUrl { get; set; }
