Regex expression: Starts with either digits/asterisks or a '+' sign, contains a min of 2 digits and ends with digits/asterisks

Question

The conditions of the regex that I'm trying to figure out are this:

• It starts with either digits/asterisks or a '+' sign and ends with digits/asterisks.

• It always requires always a minimum of 2 digits.

Example valid strings:

240*******
+12*
216438827*
*164*8827*
********21

I have been a few hours trying to solve it, but I'm stuck at this regex expression /^\+?[\d*]{2,}$/, I cannot figure out how to set the 2 min. digits requirement, so I'll really appreciate some help, thanks!

You may use

^\+?(?:\**\d){2,}\**$

See the regex demo

Details

• ^ - start of string
• \+? - an optional +
• (?:\**\d){2,} - two or more occurrences of:
  • \** - 0+ * chars
  • \d - a digit
• \** - a * symbol
• $ - end of string.
