34292-31-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 34292-31-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,2,9 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 34292-31:
(7*3)+(6*4)+(5*2)+(4*9)+(3*2)+(2*3)+(1*1)=104
104 % 10 = 4
So 34292-31-4 is a valid CAS Registry Number.

Synthesis of 1 H-indazoles and 1 H-pyrazoles via FeBr3/O 2 mediated intramolecular C-H amination
Zhang, Tianshui,Bao, Weiliang
, p. 1317 - 1322 (2013/04/10)
A new synthesis of substituted 1H-indazoles and 1H-pyrazoles from arylhydrazones via FeBr3/O2 mediated C-H activation/C-N bond formation reactions is reported. The corresponding 1,3-diaryl-substituted indazoles and trisubstituted pyr
