Check Digit Verification of cas no

The CAS Registry Mumber 81268-41-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,2,6 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 81268-41:
(7*8)+(6*1)+(5*2)+(4*6)+(3*8)+(2*4)+(1*1)=129
129 % 10 = 9
So 81268-41-9 is a valid CAS Registry Number.

Reactions of Dimethyl 1,2,4,5-Tetrazine-3,6-dicarboxylate with Nucleophiles

Kaempchen, Thomas,Massa, Werner,Overheu, Wolfgang,Schmidt, Roland,Seitz, Gunther

, p. 683 - 694 (2007/10/02)

The reaction of water, ammonia or dimethylamine with the tetrazine 1 leads via 1,4-addition of the nucleophile to the hydrazide 4 and the azines 6, 7, respectively.Contrarily methylamine yields the triazine 13.Methanol or methanethiol react to the pyrazoles 19 and 18, respectively.The structure of 18 is proved by X-ray diffraction.Depending on the p-substituents, anilines give triazoles 22 or pyrazolotriazines 24.
