Easy to remember (Posted on 2018-01-20) Difficulty: 2 of 5
Upon receiving his student's card, Danny stated that he will never
forget its 5-digit number:
"It has only three distinct digits - one pair of equal digits followed by a pair of two other equal digits and the product of the second pair in the end.
Sum of the digits is over 30."

Is the above a sufficient mnemonic aid?
