Hi  VistaDee  ,

Here are the steps you can follow：

1. Create calculated column

var _1={"A","B","C","D","E","F","G","H","I","J","K","M","L","N","O","P","Q","R","S","T","U","V","W","X","Y","Z"}
VAR _2={0,1,2,3,4,5,6,7,8,9}
var _5=IF(ISERROR(VALUE(MID('Table'[column],5,1))),BLANK(),VALUE(MID('Table'[column],5,1)))
var _6=IF(ISERROR(VALUE(MID('Table'[column],5,1))),BLANK(),VALUE(MID('Table'[column],6,1)))
var _7=IF(ISERROR(VALUE(MID('Table'[column],5,1))),BLANK(),VALUE(MID('Table'[column],7,1)))
var _8=IF(ISERROR(VALUE(MID('Table'[column],5,1))),BLANK(),VALUE(MID('Table'[column],8,1)))
RETURN
IF(LEFT('Table'[column],1) IN _1&&MID('Table'[column],2,1) IN _1&&MID('Table'[column],3,1) IN _1&&MID('Table'[column],4,1) IN _1&&
_5 IN _2 && _6 IN _2 && _7 IN _2 &&_8 IN _2,
