70937-97-2 Usage
Uses
Angiotensin I human acetate salt hydrate has been used: as an external calibration standard, it was applied to α-cyano-4-hydroxycinnamic acid (CHCA) and 2,5-dihydroxybenzoic acid (DHB) matrix, to prepare angiotensin I solution gravimetrically for hydrolysis and also used as a model peptide to demonstrate SI (système international) -traceable?amino acid analysis as an analyte to deposit on the target in the study of on-line single droplet deposition for matrix-assisted laser desorption/ionization (MALDI) mass spectrometry
General Description
Angiotensinogen (Angiotensin I) is a renin substrate, which is produced by the liver.
Biochem/physiol Actions
Angiotensin I is a putative neurotransmitter. It is the precursor of angiotensin II and of angiotensin fragment 1-7, which are the hormones involved in regulation of fluid volume and the release of aldosterone.
Purification Methods
Angiotensin is purified using extraction, affinity chromatography and HPLC [Hermann et al. Anal Biochem 159 295 1986].
Check Digit Verification of cas no
The CAS Registry Mumber 70937-97-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,9,3 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 70937-97:
(7*7)+(6*0)+(5*9)+(4*3)+(3*7)+(2*9)+(1*7)=152
152 % 10 = 2
So 70937-97-2 is a valid CAS Registry Number.
