389058-62-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 389058-62-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,8,9,0,5 and 8 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 389058-62:
(8*3)+(7*8)+(6*9)+(5*0)+(4*5)+(3*8)+(2*6)+(1*2)=192
192 % 10 = 2
So 389058-62-2 is a valid CAS Registry Number.

New orally active PDE4 inhibitors with therapeutic potential

Ochiai, Hiroshi,Ishida, Akiharu,Ohtani, Tazumi,Kusumi, Kensuke,Kishikawa, Katuya,Obata, Takaaki,Nakai, Hisao,Toda, Masaaki

, p. 29 - 32 (2004)

Structural optimization of pyrazolopyridine derivative 2, which is one of the newly discovered chemical leads for PDE4 inhibitors from our in-house library, was carried out successfully. The process of discovery of new orally active PDE4 inhibitors, which

Discovery of new orally active phosphodiesterase (PDE4) inhibitors

Ochiai, Hiroshi,Ishida, Akiharu,Ohtani, Tazumi,Kusumi, Kensuke,Kishikawa, Katuya,Yamamoto, Susumu,Takeda, Hiroshi,Obata, Takaaki,Nakai, Hisao,Toda, Masaaki

, p. 1098 - 1104 (2007/10/03)

A series of 4-anilinopyrazolopyridine derivatives were synthesized and biologically evaluated as inhibitors of phosphodiesterase (PDE4). Chemical modification of 3, a structurally new chemical lead that was found in our in-house library, was focused on 1- and 3-substituents. Full details of the discovery of a new orally active chemical lead 5 are presented. Structure-activity relationship data, pharmacological evaluation, and the subtype selectivity study are also presented.
