B decay mode (6 digit number)

1st digit : 1=B+, 2=B-, 3=B0, 4=B0bar
2nd digit : 0=D, 1=D*, 2=D0*, 3=D1, 4=D2*, 5=D1'
3rd digit : 1=+, 2=-, 3=0, 4=0bar
4th digit : 1=e-, 2=e+, 3=mu-, 4=mu+
5th digit : 1=nu_e, 2=nu_ebar, 3=nu_mu, 4=nu_mubar
6th digit : 0=no pion, 1=pi0, 2=pi+, 3=pi-

For example
Bp -> D0bar e+ nu_e : 104210
B0 -> D1- mu+ nu_mu : 332430
Bp -> D*0bar pi0 e+ nu_e : 114211
