30003-72-6 Usage

Uses

Insulin Chain B Oxidized from bovine pancreas has been used:as a matrix-assisted laser desorption/ionization (MALDI)-mass spectrometry (MS) calibration standardin electrochemical impedance spectroscopy and quartz crystal nanobalance (EQCN) studies of insulin adsorption on platinumas an internal standard to quantify insulin chain B residue in protein samples

General Description

Insulin is made up of two polypeptide chains (A and B) linked together by two disulfide linkages. Chain A and B are composed of 21 amino acids and 30 amino acids, respectively.

Biochem/physiol Actions

Insulin regulates the cellular uptake, utilization, and storage of glucose, amino acids, and fatty acids. It inhibits the breakdown of glycogen, protein, and fat. The β chain is a substrate for carboxypeptidase Y.

Check Digit Verification of cas no

The CAS Registry Mumber 30003-72-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,0,0 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 30003-72:
(7*3)+(6*0)+(5*0)+(4*0)+(3*3)+(2*7)+(1*2)=46
46 % 10 = 6
So 30003-72-6 is a valid CAS Registry Number.
