analytical chemistry and in dosimeters.
Purification Methods
A solution in warm water (0.67g/mL) is cooled rapidly to 0o, and the resulting light bluish-green monoclinic crystals are filtered at the pump, washed with cold distilled water and pressed between sheets of filter paper to dry it. The solubility at 25o is 0.36g/mL. It separates as an almost white powder when a saturated aqueous solution is diluted with EtOH.
Check Digit Verification of cas no
The CAS Registry Mumber 10045-89-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,0,4 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 10045-89:
(7*1)+(6*0)+(5*0)+(4*4)+(3*5)+(2*8)+(1*9)=63
63 % 10 = 3
So 10045-89-3 is a valid CAS Registry Number.
