Check Digit Verification of cas no

The CAS Registry Mumber 1213775-86-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,3,7,7 and 5 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1213775-86:
(9*1)+(8*2)+(7*1)+(6*3)+(5*7)+(4*7)+(3*5)+(2*8)+(1*6)=150
150 % 10 = 0
So 1213775-86-0 is a valid CAS Registry Number.

Syntheses and evaluation of the antioxidant activity of acitretin analogs with amide bond(s) in the polyene spacer

Hadjipavlou-Litina, Dimitra,Magoulas, George E.,Krokidis, Marios,Papaioannou, Dionissios

experimental part, p. 298 - 310 (2010/03/30)

Ester analogs of the antipsoriatic drug acitretin were synthesized by coupling either anilines with N-protected indole-3-carboxylic acid, followed by deprotection and coupling with O-monoprotected dicarboxylic acids or Wittig reaction of indole-3-carboxaldehyde, 3-acetyl-1-tosylpyrrole and 4-amino-9-fluorenone with Ph3P{double bond, long}CHCO2tBu, followed by N-deprotection, where necessary, and finally coupling with cinnamoyl fluorides. Corresponding free acids were obtained through TFA-mediated carboxyl group deprotection. Although these analogs and acitretin showed very low reducing abilities, analogs 5, 6, 8 and 12 strongly inhibited LOX with IC50 values ranging from 35-65 μM. Acitretin and its analogs 5-7, 10, 11 and 15 inhibited lipid peroxidation more strongly than trolox whereas acitretin and analog 4 were in vivo more potent anti-inflammatory agents on rat paw oedema induced by Carrageenan than indomethacin.
