Check Digit Verification of cas no

The CAS Registry Mumber 125240-46-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,2,4 and 0 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 125240-46:
(8*1)+(7*2)+(6*5)+(5*2)+(4*4)+(3*0)+(2*4)+(1*6)=92
92 % 10 = 2
So 125240-46-2 is a valid CAS Registry Number.

Thermally Induced Fragmentation and Cyclisation of C-Azidohydrazones

Bruche, Luca,Garanti, Luisa,Zecchi, Gaetano

, p. 619 - 624 (2007/10/02)

C-Azidohydrazones 2 were synthesized from the corresponding C-chlorohydrazones 1 and submitted to thermal decomposition in boiling benzene.Various kinds of products were obtained due to competitive modes of evolution of first-formed nitrenes 13, namely hydrogen abstraction to form aminohydrazones 3 and benzotriazepine 8, and radical fragmentation to give ultimatively diaryls 4 and arylglyoxylate arylhydrazones 5.Ring-closed products, namely 1,2,4-triazoles 6 and imidazolones 7 were also formed.
