9047-17-0 Usage
Definition
A globular protein occurringwidely in muscle tissue as anoxygen carrier. It comprises a singlepolypeptide chain and a haem group, which reversibly binds a moleculeof oxygen. This is only relinquishedat relatively low externaloxygen concentrations, e.g. duringstrenuous exercise when muscle oxygendemand outpaces supply fromthe blood. Myoglobin thus acts as anemergency oxygen store.
Purification Methods
Myoglobin is purified by CM-cellulose chromatography and Sephadex G-50 followed by chromatography on Amberlite IRC-50 Type III or BioRex 70 (<400mesh). The crystalline product as a paste in saturated (NH4)2SO4 at pH 6.5-7.0 may be stored at 4o for at least 4years unchanged, but must not be kept in a freezer.

Check Digit Verification of cas no
The CAS Registry Mumber 9047-17-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,4 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 9047-17:
(6*9)+(5*0)+(4*4)+(3*7)+(2*1)+(1*7)=100
100 % 10 = 0
So 9047-17-0 is a valid CAS Registry Number.
