General Description
BIG ENDOTHELIN-1 (1-31) is a synthetic peptide that corresponds to the N-terminal 31 amino acids of human and bovine big endothelin-1. This peptide is a potent vasoconstrictor and stimulates the release of norepinephrine in the vascular system. It also activates endothelin type A and type B receptors, and has been shown to have biological activity in various tissues and organs. BIG ENDOTHELIN-1 (1-31) is commonly used in research to study the physiological and pathological roles of endothelin-1 and its receptors, as well as to investigate potential therapeutic applications for cardiovascular diseases and other conditions involving endothelin signaling.
Check Digit Verification of cas no
The CAS Registry Mumber 133972-52-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,9,7 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 133972-52:
(8*1)+(7*3)+(6*3)+(5*9)+(4*7)+(3*2)+(2*5)+(1*2)=138
138 % 10 = 8
So 133972-52-8 is a valid CAS Registry Number.
