99895-01-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99895-01-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,8,9 and 5 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 99895-01:
(7*9)+(6*9)+(5*8)+(4*9)+(3*5)+(2*0)+(1*1)=209
209 % 10 = 9
So 99895-01-9 is a valid CAS Registry Number.

The Synthesis and Chemistry of 4-Aza-azulene
Meth-Cohn, Otto,Moore, Clive,Rooyen, Petrus H. van
, p. 1793 - 1802 (2007/10/02)
4-Aza-azulene and its 5-bromo and 6-methoxy derivatives have been efficiently synthesized by spray pyrolysis of 2-halogenoindan-1-yl azidoformates at 300 deg C and 1-2 mm pressure of nitrogen.Bromination of 4-aza-azulene gives 1-bromo, 3-bromo, and 1,3-di
