## 最终结论
```python
def is_Diff(num):
    even_sum = 0
    odd_sum = 0
    for digit in str(num):
        digit = int(digit)
        if digit % 2 == 0:
            even_sum += digit
        else:
            odd_sum += digit
    return even_sum - odd_sum == 0

# Test cases
assert is_Diff(12345) == False
assert is_Diff(1212112) == True
assert is_Diff(1212) == False
