I like to expand on romles answer:

#install.packages("stringi")
library(stringi)
string_1 = "[1] \"  .. ..$ : chr [1, 1] \\\"DM_4CRSOL\\\"\""
stri_extract(string_1, regex = '(?<=\\\\").*(?=\\\\")')

gives

[1] "DM_4CRSOL"

This does the task:
stringi::stri_extract(string_1, regex = '(?<=\\\\").*(?=\\\\")')
