97023-55-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 97023-55-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,0,2 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 97023-55:
(7*9)+(6*7)+(5*0)+(4*2)+(3*3)+(2*5)+(1*5)=137
137 % 10 = 7
So 97023-55-7 is a valid CAS Registry Number.

A facile cleavage of ketone N,N-dimethylhydrazones by CeCl3·7H2O-SiO2
Yadav,Subba Reddy,Reddy,Sabitha
, p. 1134 - 1136 (2001)
Ketone N,N-dimethylhydrazones are rapidly and chemoselectively deprotected to the corresponding ketones in high yields by CeCl3·7H2O supported on silica gel under microwave irradiation. The method is compatible with acid sensitive substrates.
