Check Digit Verification of cas no

The CAS Registry Mumber 890841-51-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,0,8,4 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 890841-51:
(8*8)+(7*9)+(6*0)+(5*8)+(4*4)+(3*1)+(2*5)+(1*1)=197
197 % 10 = 7
So 890841-51-7 is a valid CAS Registry Number.

Chroman and tetrahydroquinoline ureas as potent TRPV1 antagonists

Schmidt, Robert G.,Bayburt, Erol K.,Latshaw, Steven P.,Koenig, John R.,Daanen, Jerome F.,McDonald, Heath A.,Bianchi, Bruce R.,Zhong, Chengmin,Joshi, Shailen,Honore, Prisca,Marsh, Kennan C.,Lee, Chih-Hung,Faltynek, Connie R.,Gomtsyan, Arthur

, p. 1338 - 1341 (2011)

Novel chroman and tetrahydroquinoline ureas were synthesized and evaluated for their activity as TRPV1 antagonists. It was found that aryl substituents on the 7- or 8-position of both bicyclic scaffolds imparted the best in vitro potency at TRPV1. The most potent chroman ureas were assessed in chronic and acute pain models, and compounds with the ability to cross the blood-brain barrier were shown to be highly efficacious. The tetrahydroquinoline ureas were found to be potent CYP3A4 inhibitors, but replacement of bulky substituents at the nitrogen atom of the tetrahydroisoquinoline moiety with small groups such as methyl can minimize the inhibition.
