Check Digit Verification of cas no
The CAS Registry Mumber 35826-82-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,8,2 and 6 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 35826-82:
(7*3)+(6*5)+(5*8)+(4*2)+(3*6)+(2*8)+(1*2)=135
135 % 10 = 5
So 35826-82-5 is a valid CAS Registry Number.

Polycyclic Compounds: Part II-Structural Features of CI Disperse Red 303
Ayyangar, N. R.,Joshi, S. V.,Lugade, A. G.
, p. 842 - 845 (2007/10/02)
Commercial CI Disperse Red 303, a benzothioxanthene dye has been shown to consist of isomeric mixture of 1-methoxy-2-phenyl-3H-naphthothioxanthehe-3-one (I) and 3-methoxy-2-phenyl-1H-naphthothioxanthene-1-one (II), the orange and the red components respectively in almost equal amounts.Their structural assignments are based on spectral studies.
