How to find MS Office Product Key (CD Key) in C# with System.Management class

I fond the MS Office Version remotely by Providing IP Address (within the LAN)

Is it possible to find Product Key(CD Key) for MS Office?

Please suggest any Reference Links or sample codes

Below code is working fine to find whether MS Office is existing or not with Version

 public List<string> ReadRemoteRegistryusingWMI(string machineName, string username, string pswd)
    {
        List<string> programs = new List<string>();
        //  string programs = string.Empty;

        ConnectionOptions connectionOptions = new ConnectionOptions();

        connectionOptions.Authentication = AuthenticationLevel.Connect;
        connectionOptions.Impersonation = ImpersonationLevel.Impersonate;
        connectionOptions.Authentication = System.Management.AuthenticationLevel.PacketPrivacy;
        connectionOptions.EnablePrivileges = true;

        connectionOptions.Locale = "MS_409";

        connectionOptions.Username = username;
        connectionOptions.Password = pswd;


        ManagementScope scope = new ManagementScope("\\\\" + machineName + "\\root\\cimv2", connectionOptions);
        scope.Connect();


        string softwareRegLoc = @"Software\Microsoft\Windows\CurrentVersion\Uninstall";
        ManagementClass registry = new ManagementClass(scope, new ManagementPath("StdRegProv"), null); // select * from Win32_DisplayConfiguration


        //To Find MS Office Version
        ManagementBaseObject inParams = registry.GetMethodParameters("EnumValues"); //GetStringValue;  EnumValues //EnumKey(Actual)
        // ManagementBaseObject inParams1 = registry.
        inParams["hDefKey"] = 0x80000002;//HKEY_LOCAL_MACHINE
        inParams["sSubKeyName"] = softwareRegLoc;

        // Read Registry Key Names 
        ManagementBaseObject outParams = registry.InvokeMethod("EnumKey", inParams, null);
        string[] programGuids = outParams["sNames"] as string[];

        foreach (string subKeyName in programGuids)
        {
            inParams = registry.GetMethodParameters("GetStringValue");
            inParams["hDefKey"] = 0x80000002;//HKEY_LOCAL_MACHINE
            inParams["sSubKeyName"] = softwareRegLoc + @"\" + subKeyName;
            inParams["sValueName"] = "DisplayName";
            // Read Registry Value 
            outParams = registry.InvokeMethod("GetStringValue", inParams, null);

            if (outParams.Properties["sValue"].Value != null)
            {
                string softwareName = outParams.Properties["sValue"].Value.ToString();
                if ((softwareName.Contains("Microsoft Office")) && ((softwareName.Contains("95") || softwareName.Contains("97") || softwareName.Contains("2000") || softwareName.Contains("2002") || softwareName.Contains("2003") || softwareName.Contains("2007") || softwareName.Contains("2010") || softwareName.Contains("2013"))))
                {
                    programs.Add(softwareName);
                    //  programs=softwareName.ToString();
                    break;
                }
            }
        }
        return programs;
    }
