Hi @Raja.G

You can compare both input & output strings using the following expressions:

First 6 digits: strValue.Substring(0,6)

Last 4 digits: strValue.Substring(strValue.Length-5,4)

Hi @Raja.G ,

Try this:

"1234567891017891".Remove(6,6).Equals("123456******7891".Remove(6,6))

@Raja.G

The first expression will be valid for the first 6 values extraction. You can use the following expression to obtain last 4 values:

System.Text.RegularExpressions.Regex.Match(strValue,"\d{4}$").ToString

Hello @Raja.G
Try something like below

strCardValue1 = "1234567891011121"
strCardValue2 = "123456******7891"

If Left(strCardValue1,6) = Left(strCardValue2,6) AndAlso Right(strCardValue1,4) = Right(strCardValue2,4) then
     b_IsCardMatching = True
else
     b_IsCardMatching = False
end if

@Raja.G
Assign firstString = “2564892222"
Assign secondString = "2164892223”

Matches firstStringMatches = System.Text.RegularExpressions.Regex.Matches(firstString, “^\d{6}.\d{4}$")
Matches secondStringMatches = System.Text.RegularExpressions.Regex.Matches(secondString, "^\d{6}.\d{4}$”)

If firstStringMatches.Count > 0 AndAlso secondStringMatches.Count > 0
Assign firstMatch = firstStringMatches(0).Value
Assign secondMatch = secondStringMatches(0).Value

If firstMatch = secondMatch
    // First 6 digits and last 4 digits match
    // Add your desired actions here
Else
    // First 6 digits and last 4 digits do not match
    // Add your desired actions here
End If

End If

Hi @Raja.G

Follow the below syntax to achieve the required output. Have attached the workflow for reference.
Sequence:

  1. Assign:
    inputNumber= “1234567891011121”
  2. Assign:
    outputNumber= inputNumber.Substring(0, 6) + "**" + inputNumber.Substring(12, 4)
  3. If:
    inputNumber.Substring(0, 6) = outputNumber.Substring(0, 6) And inputNumber.Substring(12, 4) = outputNumber.Substring(12, 4)
    Then:
    Log Message: “Validation successful”
    Else:
    Log Message: “Validation failed”
