69085-44-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 69085-44-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,0,8 and 5 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 69085-44:
(7*6)+(6*9)+(5*0)+(4*8)+(3*5)+(2*4)+(1*4)=155
155 % 10 = 5
So 69085-44-5 is a valid CAS Registry Number.

4-N-alkyl-arylamino-1,2-naphthochinon-1/2-dinitrophenylhydrazones - Structure and colour
Bock,Kallmayer, Hans-Joerg
, p. 307 - 310 (2007/10/03)
The condensation products from 4-dialkylamino-1,2-naphthoquinones 2 with 2,4-dinitrophenylhydrazin (3) are thought to be as chelates 8/9. Therefore arylhydrazones 4/5 and corresponding azocompounds 6/7 can be seen as mesomeric structures. The different co
