528882-09-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 528882-09-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,8,8,8 and 2 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 528882-09:
(8*5)+(7*2)+(6*8)+(5*8)+(4*8)+(3*2)+(2*0)+(1*9)=189
189 % 10 = 9
So 528882-09-9 is a valid CAS Registry Number.

PROCESS FOR THE PREPARATION OF BENZOTRIAZEPINE DERIVATIVES

-

Page/Page column 16, (2008/06/13)

The present invention is directed to a novel process for the preparation of benzo[e][1,2,4]triazepin-2-one derivatives, useful in the preparation of gastrin and cholecystokinin receptor ligands.

Novel, achiral 1,3,4-benzotriazepine analogues of 1,4-benzodiazepine-based CCK2 antagonists that display high selectivity over CCK1 receptors

, p. 2253 - 2261 (2007/10/03)

A series of 1,3,4-benzotriazepine-based CCK2 antagonists have been devised by consideration of the structural features that govern CCK receptor affinity and the receptor subtype selectivity of 1,4-benzodiazepine- based CCK2 antagonists. In contrast to the latter compounds, these novel 1,3,4-benzotriazepines are achiral, yet they display similar affinity for CCK2 receptors to the earlier molecules and are highly selective over CCK1 receptors.
