Hint 1
Notice the way that some of the upper case letters are followed by a lower case letter in the elements of the first part of the expression.
Hint 2
Use addition to get a total for the symbols that are adjacent rather than just running the numbers together.
Solution
 Replacing the letters in the first part of the expression with the atomic weights from a Table of the Elements results in:
 Ac - Actinium - 89
 C - Carbon - 6
 U - Uranium - 92
 Se - Selenium - 34
 ---
 221
 H - Hydrogen - 1
 I - Iodine - 53
 S - Sulfur - 16
 ---
 70
 Si - Silocon - 14
 C - Carbon - 6
 K - Potassium - 19
 Ne - Neon - 10
 S - Sulfur - 16
 S - Sulfur - 16
 ---
 81
 221 + (70 - 81) = 210
Reversing that kind of process and replacing the numbers in the latter part of the expression results in:
 84 - Polonium - Po
 53 - Iodine - I
 16 - Sulfur - S
 8 - Oxygen - O
 7 - Nitrogen - N
 53 - Iodine - I
 8 - Oxygen - O
 7 - Nitrogen - N
 16 - Sulfur - S
 PoISON - IONS = Po - Polonium
The answer is stl.la/210polonium. The short links stl.la/210-polonium, stl.la/polonium210 and stl.la/polonium-210 also work (but not stl.la/210po).
