+# --description--
+
+A **CUSIP** is a nine-character alphanumeric code that identifies a North American financial security for the purposes of facilitating clearing and settlement of trades. The CUSIP was adopted as an American National Standard under Accredited Standards X9.6.
+
+# --instructions--
+
+Write a function that takes a string as a parameter and checks if the string is valid CUSIP.
+
+# --hints--
