input1 =  '( active parts ) acetylene cas89343-06-6'

One liner:

' '.join([*filter(lambda x: "cas" not in x, input1.split())])

Use re.sub with the pattern \b[\w-]*cas[\w-]*\b, and replace with a single space, then trim the output:

string_s = '( active parts ) acetylene cas89343-06-6'
output = re.sub(r'\b[\w-]*cas[\w-]*\b', ' ', string_s).strip()
print(string_s + '\n' + output)

This prints:

( active parts ) acetylene cas89343-06-6
( active parts ) acetylene

you can do this by:-

string = "hello how are you"
character = "a"
newString = []
for i in string.split(' '):
    if not character in i:
        newstring.append(i)
newString = ' '.join(newString)
