目前SN计算已经可以完全自定义了，也就是凭空生成正确规范的SN，不需要已知正确SN
但是
sn能否在官网验证通过，需要两个条件，一sn本身符合规范（通过计算获取的SN一定是规范的），二官方数据库录入了该sn
BB值加1就代表前面有1000个sn了，你要是改到99那就是前面有99000个sn

你会发现大量连续的号被同一个邮箱注册，这些基本是被号贩子注册了，所以大家尽量不要公开自己的号

像这个段，理论上可以容纳999999个，但是这个要看当时出厂规模，不是所有的号都会进入数据库的，而是生产了多少台就登记多少
sn：1750PDN179400 mac：0011323B0CC3
1750属于早期的机器可以看出当初这个段的序列号就生产了200台，所以当输入201台的序列号就会提示无效

CCY0PDNAAA#BB

CC为下面公式中mod CC (猜测八九不离十)
Y0估计为批次号，Y值为1-9，可以是A，B，C，计算的时候用0，1，2代替
PDN代表918机型
AAA三位十进制数代表第AAA个号

一位数代表由CC个数组成的循环数组

BB两位十进制数每当AAA到999的时候BB进1，这个数值不要太大一般控制在15以内，比如1750PDN999800之后就是1750PDN000901
