66903-18-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 66903-18-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,9,0 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 66903-18:
(7*6)+(6*6)+(5*9)+(4*0)+(3*3)+(2*1)+(1*8)=142
142 % 10 = 2
So 66903-18-2 is a valid CAS Registry Number.

Non anticholinergic gastric acid secretion inhibitors. New piperazine and related derivatives
Tricerri,Elitropi,Panto,et al.
, p. 555 - 562 (2007/10/08)
Some of the new piperazine derived compounds exhibited interesting gastric antisecretory properties without anticholinergic action. 1 Piperonyl 4 (3,7,11 trimethyl 2,6,10 dodecatrienyl) piperazine was the most active as an antisecretory agent in rat. Some analogous compounds, with the piperazine ring replaced by other heterocyclic or acyclic amines, were also prepared. Structure activity relationships are discussed.
