Mnemonic for the remaining decimal places is using major system only:

 

(Disclaimer: This is not to hurt any person and do not in anyways express my opinion. It is only meant to be humorous, so that I could remember the mnemonic easily)

Major System (Refine this list):

0

s, z, soft c

"z" is the first letter of zero. The others have a similar sound

1

d, t

d, t have one downstroke and sound similar(some variants include th)

2

N

n has two downstrokes

3

M

three downstrokes , also "m" looks like a "3" on its side

4

R

last letter of four, also 4 and R are almost mirror images of each other

5

L

L is the Roman Numeral for 50

6

j, sh, soft ch, dg, zh, soft g

a script j has a lower loop / g is almost a 6 flipped over

7

k, hard c, hard g, q, qu

capital K contains two sevens

8

f, v

script f resembles a figure-8. V sounds similar. (some variants include th)

9

b, p

p is a mirror-image 9. b sounds similar and resembles a 9 rolled around

Unassigned

Vowel sounds, w,h,y

These can be used anywhere without changing a word's number value

 

Note: When there are two same adjacent letters, consider only 1. Eg: mapped mean 391, not 3991. Also sound is important, not the letters, eg: Michael stands for 375. Also, g (hard) is 7, not 8. Also, nympho is 238 not 239.
