188889-27-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 188889-27-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,8,8 and 9 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 188889-27:
(8*1)+(7*8)+(6*8)+(5*8)+(4*8)+(3*9)+(2*2)+(1*7)=222
222 % 10 = 2
So 188889-27-2 is a valid CAS Registry Number.

Synthesis and biological activity of high-affinity retinoic acid receptor antagonists

Johnson, Alan T.,Wang, Liming,Standeven, Andrew M.,Escobar, Maria,Chandraratna, Roshantha A.S.

, p. 1321 - 1338 (1999)

This article reports the synthesis and biological activity of new high affinity retinioic acid receptor (RAR) antagonists. The effect of introducing heteroatoms in the bicyclic ring system of the potent dihydronaphthalene RAR antagonist 8, and the variation of the pendant aromatic group on the ability of these compounds to function as RAR antagonists is discussed. The use of binding, transcriptional, and in vivo assays revealed that the 2,2-dimethylthiochromene analogue 59, and the 2,2-dimethylchromene derivative 85, were the most effective in blocking retinoid agonist induced activity.
