404000-65-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 404000-65-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,4,0,0 and 0 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 404000-65:
(8*4)+(7*0)+(6*4)+(5*0)+(4*0)+(3*0)+(2*6)+(1*5)=73
73 % 10 = 3
So 404000-65-3 is a valid CAS Registry Number.

Thiophene inhibitors of PDE4: Crystal structures show a second binding mode at the catalytic domain of PDE4D2

Nankervis, Jacob L.,Feil, Susanne C.,Hancock, Nancy C.,Zheng, Zhaohua,Ng, Hooi-Ling,Morton, Craig J.,Holien, Jessica K.,Ho, Patricia W.M.,Frazzetto, Mark M.,Jennings, Ian G.,Manallack, David T.,John Martin,Thompson, Philip E.,Parker, Michael W.

PDE4 inhibitors have been identified as therapeutic targets for a variety of conditions, particularly inflammatory diseases. We have serendipitously identified a novel class of phosphodiesterase 4 (PDE4) inhibitor during a study to discover antagonists of the parathyroid hormone receptor. X-ray crystallographic studies of PDE4D2 complexed to four potent inhibitors reveal the atomic details of how they inhibit the enzyme and a notable contrast to another recently reported thiophene-based inhibitor.
