EXAMPLE

225 is in the sequence as 225 is divisible by 2 + 2 + 5 = 9 but not by 2 while 2 is a digit of 225. - David A. Corneth, Jan 28 2021

PROG

(PARI) is(n) = { my(d = digits(n), sd = vecsum(d), s = Set(d)); if(sd != 0 && n % sd == 0, if(s[1] == 0, return(1) ); for(i = 1, #s, if(n % s[i] != 0, return(1) ) ); 0 ); 0 } \\ David A. Corneth, Jan 28 2021
