As of 10/7/2015, no live official trademarks were found on USPTO.gov for the exact term/number
Therefore, this is an extremely lucky domain.
In the West, a 9-number domain may seem too long and mean little to average Occidentals; heck, we don't fully understand the premise, either. However...
In the Chinese market, "8" is the luckiest number.
Despite popular belief among Westerners, "4" is not always unlucky, as shown on Travel China Guide; 4 represents the following in the natural world:
Earth, Water, Fire, and Wind
East, West, South, and North
Spring, Summer, Fall, and Winter
4 also has numerous positive connotations in Chinese culture, as listed on the above website.
From a Western point-of view, this domain exhibits some well defined patterns; along with the obvious flanking triple 8's, the 543 numbers are in backward numeral order.
Long repeating 8's are prized as well. In fact, 5, 6, 7, 8, 9, and even 10+ repeating 8's are commanding excellent prices these days.
Evidently, every possible string of 8's have been registered in .com, all the way up to the longest one.
Finally, repeating 8's with other lucky numerals are becoming rare as hand registrations (fresh from the registrar) and are also highly prized.
The Chinese market for numerals is HUGE.
