72957-43-8 Usage
General Description
(Ortho-nitrophenyl)sulfenyl pentagastrin is a chemical compound that is used in medical research for its ability to stimulate gastric acid secretion and to induce gastric lesions in experimental animal models. It is a synthetic form of the hormone gastrin, which plays a key role in the regulation of gastric acid production and the maintenance of the gastric mucosal barrier. The addition of the (ortho-nitrophenyl)sulfenyl group to the pentagastrin molecule enhances its stability and prolongs its biological activity, making it a valuable tool for studying the physiology and pathophysiology of the stomach and the digestive system. (ortho-nitrophenyl)sulfenyl pentagastrin is also used in pharmaceutical research for the development of drugs targeting gastric acid secretion and gastrointestinal disorders.
Check Digit Verification of cas no
The CAS Registry Mumber 72957-43-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,9,5 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 72957-43:
(7*7)+(6*2)+(5*9)+(4*5)+(3*7)+(2*4)+(1*3)=158
158 % 10 = 8
So 72957-43-8 is a valid CAS Registry Number.
