131844-00-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 131844-00-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,8,4 and 4 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 131844-00:
(8*1)+(7*3)+(6*1)+(5*8)+(4*4)+(3*4)+(2*0)+(1*0)=103
103 % 10 = 3
So 131844-00-3 is a valid CAS Registry Number.

Potential histamine H2-receptor antagonists. Synthesis, conformational studies and activity of novel 3-oxo-1,2,5-thiadiazole 1,1-dioxide derivatives.

Aran,Davila,Frances,Goya,Gras,Martinez,Mylonakis,Pardo

, p. 1003 - 1007 (2007/10/02)

New histamine H2-receptor antagonists bearing a novel "urea equivalent", the 3-oxo-1,2,5-thiadiazole 1,1-dioxide ring, have been synthesized in a transamination reaction. Open chain derivatives have also been obtained. Theoretical conformational analysis of the compounds has been carried out using a molecular modelling program. Semiempirical CNDO/2 calculations have also been performed. The antisecretory and cytoprotective activities of the compounds have been evaluated.
