What is "shagarakti-shuriash"

Šagarakti-Šuriaš, written phonetically ša-ga-ra-ak-ti-šur-ia-aš or ša-garak-ti-šu-ri-ia-aš in cuneiform or in a variety of other forms, Šuriaš (a Kassite sun god corresponding to Babylonian Šamaš, and possibly to Vedic Surya) gives me life, (1245–1233 BC short chronology) was the twenty seventh king of the Third or Kassite dynasty of Babylon. The earliest extant economic text is dated to the 5th day of Nisan in his accession year, corresponding to his predecessor’s year 9, suggesting the succession occurred very early in the year as this month was the first in the Babylonian calendar. He ruled for thirteen years and was succeeded by his son, Kaštiliašu IV.
