Check Digit Verification of cas no

The CAS Registry Mumber 311786-69-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,1,7,8 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 311786-69:
(8*3)+(7*1)+(6*1)+(5*7)+(4*8)+(3*6)+(2*6)+(1*9)=143
143 % 10 = 3
So 311786-69-3 is a valid CAS Registry Number.

An unexpected valence bond isomerization to the heteroaromatic ring system: [1,2,3]triazolo[4,5-d]pyridazine

Koever, Peter,Hajos, Gyoregy,Riedl, Zsuzsanna,Parkanyi, Laszlo,Kollenz, Gert

, p. 1785 - 1786 (2007/10/03)

The arylazo substituted salt 2 when treated with a base underwent a valence bond isomerization to yield a derivative of the heteroaromatic ring system, [1,2,3]triazolo[4,5-d]pyridazine (4).
