129109-04-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129109-04-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,1,0 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 129109-04:
(8*1)+(7*2)+(6*9)+(5*1)+(4*0)+(3*9)+(2*0)+(1*4)=112
112 % 10 = 2
So 129109-04-2 is a valid CAS Registry Number.

2,3-Dichloro- and 2,5-dichloropyrazines were treated with sodium azide.The former gave diazidopyrazines and the latter, monoazidomonochloropyrazines.Pyrolysis of 2,3-diazidopyrazines resulted the production of 1,2-dicyanoiminoethanes and that of 2-azido-5
