Puzzle - RPL and others
For the RPL (Let's make it an HP-50G oriented contest), judge by bytes x execution time.

Problem: Social Security Numbers in the USA always have 9 digits. My friend has a very unusual social security number. The first two digits on the left are evenly divisible by 2, the first three digits are evenly divisible by three... and yes, it continues up that way all the way to the last digit... The first 8 digits on the left are evenly divisible by 8 and the full 9 digit number is evenly divisible by 9.

What is my friend's social security number?

Note: This number is 9 digits long, it does not contain any zeroes and no digits are repeated in the number. Also, putting the number on the stack inside the << and >> will not be considered a solution to this problem.



For the other machines, post your solution and let's see what can be done.

PLEASE DO NOT POST the actual number until about 18 hours after this post ? (6am EASTERN USA TIME 4/23/21). :-)

As always have fun.
