Most ink companies will special mix and match inks to color samples provided.
Once someone develops a formula it should be easy for others to duplicate.
Your printer should be able to take care of this for you.
If you are just looking for a close match, I go to Photoshop. Double click on your color swatch in the toolbar. Color chart
( they call it color picker) will come up, enter your color values in the CMYK boxes, then click on the custom bar. This will open up another box,where on it shows the closest PMS color which in your case is PMS 349. Click back on the Picker button and it takes you back to the previous box and shows PMS 349's CMYK build which is C-97 / M-35 / Y-100 / K-32.
It is not exact, but it comes real close. Your Graphics person should be able to do this easily for you. Pantone also has a PMS book that has the cross reference for major pantone colors. Hope you can understand my instructions, hard to put on paper sometimes what the brain is thinking. Ken
They make a designer series pantone book which has a ton of the different colors and gives the CMYK build to it. It does not give you a PMS number but it will show you what the color really looks like if your monitor is not ICC profiled. The other book is a PMS bridge. That will give you the cmyk version of the PMS color. Most cases the match is terrible especially with inks that are Reflex blue and orange.
I happen to use the free Pantone application called "myPantone Pallets"
myPANTONE™ palettes software provides innovative tools for creating, managing and sharing user-defined and PANTONE-identified color palettes. Features an eye-dropper for picking desktop colors, color harmonies, auto-generating palettes from imported images and the ability to save, print and also share palettes through the myPANTONE online community.
