Are the Latin word 'octo' is derived from the serial number of the letter 'h' in the alpabet?

Are the Latin word "octo" is derived from the serial number of the letter "h" in the alpabet?

The latin words "veho" and "traho" transform into the latin words "vecto" and "tracto" respectively by analogy with the English word "bear" transforms into the English word "bring". The latin language also has the word "octo". I have tried to reconstruate it origin.

The origin verb The perfect passive participle The derivative verb
veho vectus vecto
traho tractus tracto
?oho? ?octus? octo

a 1
b 2
c 3
d 4
e 5
f 6
g 7
h 8




For better understanding the question:

The origin verb The past passive participle The derivative verb
bear born bring
