49852-99-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 49852-99-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,8,5 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 49852-99:
(7*4)+(6*9)+(5*8)+(4*5)+(3*2)+(2*9)+(1*9)=175
175 % 10 = 5
So 49852-99-5 is a valid CAS Registry Number.

, p. 99 - 102 (2007/10/03)
A number of aminonitroanthraquinone autocomplexes with a one-membered NH bridge were synthesized from 1,5-dinitroanthraquinone and substituted aromatic amines. Intramolecular charge transfer in the products was studied by spectral methods.
