7724-15-4 Usage
Chemical Properties
off-white powder
Uses
Fluorescent probe for protein conformation studies.
Purification Methods
Crystallise the acid twice from 2% aqueous KOH and dry it under high vacuum for 4hours at room temperature. It also crystallises from H2O. It is tested for purity by TLC on silica gel with isopropanol as solvent. The free acid is obtained by acidifying a saturated aqueous solution. [Beilstein 14 H 762.]
Check Digit Verification of cas no
The CAS Registry Mumber 7724-15-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,2 and 4 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7724-15:
(6*7)+(5*7)+(4*2)+(3*4)+(2*1)+(1*5)=104
104 % 10 = 4
So 7724-15-4 is a valid CAS Registry Number.
