97909-22-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 97909-22-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,9,0 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 97909-22:
(7*9)+(6*7)+(5*9)+(4*0)+(3*9)+(2*2)+(1*2)=183
183 % 10 = 3
So 97909-22-3 is a valid CAS Registry Number.

CATALYTIC TRANSAMINATION OF DIALKYLAMINO-o-QUINONES
Tsizin, Yu. S.,Chernyak, S. A.,Kornienko, N. I.
, p. 2381 - 2388 (2007/10/02)
The ions of transition and alkaline-earth metals catalyze the transamination of bicyclic dialkylamino-o-quinones by primary and secondary amines.The effectiveness of the catalysis is determined by the type of chelate complex formed by the o-quinones and b
