442562-81-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 442562-81-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,2,5,6 and 2 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 442562-81:
(8*4)+(7*4)+(6*2)+(5*5)+(4*6)+(3*2)+(2*8)+(1*1)=144
144 % 10 = 4
So 442562-81-4 is a valid CAS Registry Number.

Page/Page column 87-88, (2008/06/13)
Compounds are described that are active on PDE4. Also described are crystal structures of PDE4B determined using X-ray crystallography, the use of PDE4B crystals and strucural information for identifying molecular scaffolds, for developing ligands that bind to and modulate PDE4B, and for identifying improved ligands based on known ligands.
