136304-94-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 136304-94-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,3,0 and 4 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 136304-94:
(8*1)+(7*3)+(6*6)+(5*3)+(4*0)+(3*4)+(2*9)+(1*4)=114
114 % 10 = 4
So 136304-94-4 is a valid CAS Registry Number.

Page/Page column 24, (2010/11/24)

A medicament having an inhibitory activity against hematopoietic prostaglandin D2 synthase, which comprises as an active ingredient a compound represented by the following general formula (I) or a salt thereof: wherein X represents a group represented by the formula —N═C(R5)— or the formula —NH—CH(R5)—, R1, R2, R3, and R4 represent a hydrogen atom, a halogen atom, a C1 to C6 alkyl group, or a hydroxy group, R5 represents a C1 to C6 alkyl group or a C6 to C10 aryl group, and R represents an amino group.

Synthesis and structure-activity relationships of N-substituted 2-[(2-imidazolylsulfinyl)methyl]anilines as a new class of gastric H+/K+-ATPase inhibitors

Yamakawa,Matsukura,Nomura,Yoshioka,Masaki,Igata,Okabe

, p. 1746 - 1752 (2007/10/02)

A series of N-substituted 2-[(2-imidazolylsulfinyl)methyl]anilines was synthesized and evaluated for its biological activity against H+/K+-ATPase prepared from rabbit stomach and gastric acid secretions in Heidenhain pouch dogs. Monoalkyl substituents on the nitrogen atom of the aniline moiety markedly inhibited the enzyme activity to the same degree as omeprazole, a representative H+/K+-ATPase inhibitor. Most of these compounds, administered at 3 mg/kg i.v. inhibited histamine-stimulated gastric acid secretion. The inhibitory activity of these derivatives on the enzymes at pH 6.0 was more potent than that at pH 7.4, and was distinctly correlated to stability in aqueous solution at pH 5.0.
