It is called Kuntalam in Muthuswami Dikshitar school of Carnatic music.
The mnemonic phrase is sa ri gu mi pa dha na.
[3] Its ārohaṇa-avarohaṇa structure (ascending and descending scale) is as follows (see swaras in Carnatic music for details on below notation and terms): (the notes used in this scale are chathusruthi rishabham, antara gandharam, prati madhyamam, shuddha dhaivatham, shuddha nishadham) As it is a melakarta rāgam, by definition it is a sampoorna rāgam (has all seven notes in ascending and descending scale).
[3] Kantamani has a couple of minor janya rāgams (derived scales) associated with it.
Kantamani's notes when shifted using Graha bhedam, yields Manavati melakarta rāgam.
