Difference between R134a and 134a?

I hope I didn't screw up. I charged the a/c on my VW and after the fact realized the can I used just said 134a on it. Is that the same as R134a or do I have a problem now? thanks

It's the same most likely. No expert, but it was just refrigerant wasn't it..not leak detector or some sort of conversion kit product? Did it say "compatible" on it somewhere?

1,1,1,2-Tetrafluoroethane, R-134a, Genetron 134a, Suva 134a or HFC-134a, is a haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane), but with less ozone depletion potential. It has the formula CH2FCF3, and a boiling point of −26.3 C (−15.34 F) at atmospheric pressure.

Recently, 1,1,1,2-tetrafluoroethane has been subject to use restrictions due to its contribution to climate change. In the EU, it will be banned as of 2011 in all new cars.[2] The Society of Automotive Engineers (SAE) has proposed 1,1,1,2-tetrafluoroethane (HFC-134a) to be best replaced by a new fluorochemical refrigerant HFO-1234yf (CF3CF=CH2) in automobile air-conditioning systems.[3] California may also prohibit the sale of canned 1,1,1,2-tetrafluoroethane to individuals to avoid non-professional recharge of air conditioners.[4] A ban has been in place in Wisconsin since October 1994 under ATCP 136 prohibiting sales of container sizes holding less than 15 lbs of 1,1,1,2-tetrafluoroethane, but this restriction applies only when the chemical is intended to be a refrigerant.[5] It appears, for example, that it is legal for a person to purchase gas duster containers with any amount of the chemical because in that instance the chemical is neither intended to be a refrigerant [5] nor is HFC-134a included in the 7671a listing of class I and class II substances.[6]
