133307-22-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 133307-22-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,3,0 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 133307-22:
(8*1)+(7*3)+(6*3)+(5*3)+(4*0)+(3*7)+(2*2)+(1*2)=89
89 % 10 = 9
So 133307-22-9 is a valid CAS Registry Number.

IMIDAZO[5,1-C][1,2,4]BENZOTRIAZINE DERIVATIVES AS INHIBITORS OF PHOSPHODIESTERASES

-

Page/Page column 21, (2010/06/11)

The invention relates to imidazo[5,1-c][1,2,4]benzotriazine derivatives of formula I: which are inhibitors of phosphodiesterase 2 or 10 useful in treating central nervous system diseases such as psychosis and also in treating, for example, obesity, type 2 diabetes, metabolic syndrome, glucose intolerance, and pain.

Novel compounds possessing potent cAMP and cGMP phosphodiesterase inhibitory activity. Synthesis and cardiovascular effects of a series of imidazo[1,2-a]quinoxalinones and imidazo[1,5-a]quinoxalinones and their aza analogues

, p. 2671 - 2677 (2007/10/02)

A series of novel imidazoquinoxalinones and their aza analogues were prepared by the cyclization of o-amino(1H-imidazol-1-yl)aryls and heteroaryls with carbonyldiimidazole. The compounds were screened for inhibition of Type I and Type IV phosphodiesterase
