. ▁The ▁RUN ▁is ▁also ▁the ▁Un ique ▁Tax ▁Ro le ▁of ▁natural ▁persons . ▁ ▁The ▁RUN ▁and ▁the ▁R UT ▁consist ▁of ▁two ▁parts ▁separated ▁by ▁a ▁hy phen : ▁the ▁correl ative ▁number ▁and ▁the ▁ver ifying ▁digit ▁or ▁D V . ▁The ▁D V ▁consists ▁of ▁a ▁digit ▁that ▁goes ▁from ▁ 0 ▁to ▁ 9 ▁or ▁the ▁letter ▁K , ▁which ▁is ▁obtained ▁from ▁the ▁correl ative ▁via ▁an ▁algorithm . ▁The ▁D V ▁valid ates ▁the ▁RUN ▁or ▁R UT , ▁since ▁this ▁number ▁can ▁have ▁only ▁one ▁ver ifying ▁digit ; ▁this ▁way ▁mistakes ▁in ▁typing ▁and ▁de ception ▁are ▁avoided . ▁ ▁Norm ally , ▁both ▁the ▁RUN ▁and ▁the ▁R UT ▁use ▁separator ▁points ▁of ▁thousands , ▁so ▁they ▁obey ▁the ▁following ▁format : ▁XX . XXX . XXX - Y , ▁where ▁X ▁is ▁a ▁digit ▁and ▁Y ▁is ▁a ▁digit ▁or ▁the ▁letter ▁K . ▁ ▁References ▁▁ ▁Category : Ch ile an ▁law ▁Category : Ident ifiers ▁Category : 1 9 7 3 ▁in ▁Chile an ▁law <0x0A> </s> ▁In ▁ 1 9 5 6 , ▁the ▁US ▁State ▁Department ▁created ▁the ▁Jazz ▁Amb ass adors ▁program , ▁h iring ▁leading ▁American ▁Jazz ▁mus icians ▁such ▁as ▁ ▁Louis ▁Arm strong , ▁D iz zy ▁G illes pie , ▁Ben ny ▁Good man , ▁and ▁Duke ▁Ell ington ▁to ▁be ▁" amb ass adors " ▁for ▁the ▁United ▁States ▁over se as , ▁particularly ▁to ▁improve ▁the ▁public ▁image ▁of ▁the
