12179-04-3 Usage
Uses
Used in large amounts in making insulating fi berglass and sodium perborate bleach.
Chemical Properties
Borax is a noncombustible (an inherent
fire retardant), bluish-gray or green, odorless crystalline
powder or granules.
General Description
White odorless crystals or free-flowing powder. Density: 1.82 g cm-3. Soluble in water (38 g / L H2O at 20°C). Used in the manufacture of fiberglass insulation and sodium perborate bleach.
Reactivity Profile
Sodium tetraborate pentahydrate is non-combustible. Dissolves somewhat exothermically in water to give basic solutions. Of generally low chemical reactivity. When heated in a closed tube, starts to melt in its own water of crystallization at 128°C and becomes fluid at 140°C. When heated in the open, loses water of crystallization and then melts at 742°C.
Hazard
A severe eye irritant.

Check Digit Verification of cas no
The CAS Registry Mumber 12179-04-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,1,7 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 12179-04:
(7*1)+(6*2)+(5*1)+(4*7)+(3*9)+(2*0)+(1*4)=83
83 % 10 = 3
So 12179-04-3 is a valid CAS Registry Number.
