Check Digit Verification of cas no

The CAS Registry Mumber 882427-74-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,2,4,2 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 882427-74:
(8*8)+(7*8)+(6*2)+(5*4)+(4*2)+(3*7)+(2*7)+(1*4)=199
199 % 10 = 9
So 882427-74-9 is a valid CAS Registry Number.

First chemical synthesis of three natural depsides involved in flavonol catabolism and related to quercetinase catalysis

Tranchimand, Sylvain,Tron, Thierry,Gaudin, Christian,Iacazio, Gilles

, p. 587 - 597 (2007/10/03)

We report here the first chemical synthesis of three depsides related to quercetinase-catalyzed degradation of kaempferol, quercetin, and myricetin. The three depsides were constructed through the coupling of suitably protected phloroglucinol carboxylic acid and hydroxy-perbenzylated, derivatives of gallic, protocatechuic, and 4-hydroxy benzoic acids. The three synthesized target compounds proved to be identical to their natural counterparts, arising from quercetinase action on corresponding flavonols. Copyright Taylor & Francis Group, LLC.
