138559-57-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138559-57-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,5,5 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 138559-57:
(8*1)+(7*3)+(6*8)+(5*5)+(4*5)+(3*9)+(2*5)+(1*7)=166
166 % 10 = 6
So 138559-57-6 is a valid CAS Registry Number.

Serotoninergic 5-HT3 and 5-HT4 receptor activities of dihydrobenzofuran carboxylic acid derivatives
Fancelli,Caccia,Fornaretto,McArthur,Severino,Vaghi,Varasi
, p. 263 - 266 (1996)
Structure-activity relationships in a series of dihydrobenzofuran derivatives related structurally to the 5-HT3 antagonist and 5-HT4 agonist ADR 932 (I) were investigated. Members of this series, such as (18) and (23), were found to be 5-HT4 agonist or partial agonists endowed with remarkably high affinity and selectivity.
