2944-13-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2944-13-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,4 and 4 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2944-13:
(6*2)+(5*9)+(4*4)+(3*4)+(2*1)+(1*3)=90
90 % 10 = 0
So 2944-13-0 is a valid CAS Registry Number.

REACTIVITY OF AMIDINES OF THE ANTHRAQUINONE SERIES. II. NITRATION
Shapkin, V. P.,Popov, S. I.
, p. 930 - 935 (2007/10/02)
By the nitration of 1-arylamino- and α,α'-diarylaminoanthraquinones in acetic acid it is possible to obtain high yields of products with the nitro group at the ortho position in the aryl residue if the para position is occupied and at the para position if
