25771-23-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 25771-23-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,7,7 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 25771-23:
(7*2)+(6*5)+(5*7)+(4*7)+(3*1)+(2*2)+(1*3)=117
117 % 10 = 7
So 25771-23-7 is a valid CAS Registry Number.

In pursuit of non narcotic analgetic and antiinflammatory agents. 1 carboxyalkyl 3 acylindoles
Allais,Meier,Mathieu,et al.
, p. 187 - 199 (2007/10/08)
The synthesis and study of different carboxyalcoyl 1 acyl 3 indoles has led to molecules endowed with analgesic properties associated with an anti inflammatory action of variable importance. In particular carboxymethyl 1 p chlorobenzoyl 3 methoxy 6 indole (RU 3959) has a strong analgesic activity and a remarkable tolerance which have been confirmed in clinical trials.
