7784-25-0 Usage

Description

Ammonium aluminum sulfate, NH4AI(S04)2·12H2O, is colorless, odorlesswater-soluble crystals. Also known as ammonium alum,aluminumammonium sulfate,it is used in manufacturing medicines and baking powder, and in dyeing,tanning,andpapermaking.

Chemical Properties

Colorless crystals; odorless; strong astringent taste. Soluble in water and glycerol; insoluble in alcohol.

Uses

Aluminum Ammonium Sulfate is a general purpose food additive that functions as a buffer and neutralizing agent. its solubility is 1 g in 7 ml of water at 25°c and 1 g in 0.3 ml of boiling water. it is used in baking powders.

Safety Profile

Irritating if inhaled or ingested. Upon decomposition it emits toxic fumes of NOx and SOx,.

Check Digit Verification of cas no

The CAS Registry Mumber 7784-25-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 4 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7784-25:
(6*7)+(5*7)+(4*8)+(3*4)+(2*2)+(1*5)=130
130 % 10 = 0
So 7784-25-0 is a valid CAS Registry Number.
