289903-29-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 289903-29-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,9,0 and 3 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 289903-29:
(8*2)+(7*8)+(6*9)+(5*9)+(4*0)+(3*3)+(2*2)+(1*9)=193
193 % 10 = 3
So 289903-29-3 is a valid CAS Registry Number.

Phenolic modification as an approach to improve the pharmacology of the 3-acyloxy-2-benzylpropyl homovanillic amides and thioureas, a promising class of vanilloid receptor agonists and analgesics

, p. 1171 - 1179 (2007/10/03)

In order to improve the analgesic activity and pharmacokinetics of thioureas 2 and 3, which we previously developed as potent vanilloid receptor (VR) agonists, we prepared and characterized phenolic modifications of them and of their amide surro-gates (7, 8). The aminoethyl analogue of the amide template 13 was a potent analgesic with an EC50 =0.96 μg/kg in the AA-induced writhing test and with better in vivo stability than the parent phenol. Copyright
