It is called Rasamanjari in Muthuswami Dikshitar school of Carnatic music.
The mnemonic phrase is sa ru gu mi pa dhu nu.
[1] Its ārohaṇa-avarohaṇa structure (ascending and descending scale) is as follows (see swaras in Carnatic music for details on below notation and terms): (the scale uses the notes shatsruthi rishabham, antara gandharam, prati madhyamam, shatsruthi dhaivatham, kakali nishadham) As it is a melakarta rāgam, by definition it is a sampoorna rāgam (has all seven notes in ascending and descending scale).
Rasikapriya has a few minor janya rāgams (derived scales) associated with it.
Rasikapriya's notes when shifted using Graha bhedam, yields 2 other major melakarta rāgams, namely, Mayamalavagowla (rāgam using which first lessons are taught to beginners) and Simhendramadhyamam.
