99504-70-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99504-70-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,5,0 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 99504-70:
(7*9)+(6*9)+(5*5)+(4*0)+(3*4)+(2*7)+(1*0)=168
168 % 10 = 8
So 99504-70-8 is a valid CAS Registry Number.

Preparation of hydrazonates from orthoesters and phenylhydrazine
Br?tulescu, George
, p. 559 - 560 (2008/09/16)
Eight hydrazonates were prepared by an original method in heterogeneous medium on alumina support and microwaves. The irradiation time was between six and nine minutes and the yields were good. The products were characterised by elemental analysis and IR spectroscopy.
