22490-64-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 22490-64-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,4,9 and 0 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 22490-64:
(7*2)+(6*2)+(5*4)+(4*9)+(3*0)+(2*6)+(1*4)=98
98 % 10 = 8
So 22490-64-8 is a valid CAS Registry Number.

Chemical studies on the chiral indanone derivatives as the inhibitor of Renilla luciferase

Wu, Chun,Nakamura, Hideshi,Murai, Akio,Inouye, Satoshi

, p. 9575 - 9583 (2007/10/03)

The bioluminescence reaction of coelenterazine involves an oxidative process. To investigate the reaction mechanism, we synthesized three mechanism-based inhibitors with an indanone core structure. The inhibitors exhibited the competitive inhibition of the Renilla luciferase reaction. The (-)-4-benzyl-2-(4-hydroxybenzyl)-2-hydroxymethyl-6-(4-hydroxyphenyl)-indan- 1-one showed the significant enantio-selectivity of the inhibition and its absolute configuration was assigned as the R-configuration. These inhibitors could be useful probes to study the catalytic environment in the coelenterazine-luciferase reaction.
