$\text { CSD formula must produce 1. CSD } = [ 210 - 3 ( 0 + e + 1 + 0 + 0 + 2 ) - ( 7 + 3 + 0 + 0 + 4 ) ] _ { \bmod ( 10 ) } = [ 210 -$ $3 ( \mathrm { e } + 3 ) - 14 ) ] _ { \bmod ( 10 ) } = [ 210 - 23 - 3 \mathrm { e } ] _ { \bmod ( 10 ) } = [ 187 - 3 \mathrm { e } ] _ { \bmod ( 10 ) } = 1 \rightarrow \mathrm { e } = 2$
