Description
Calcium tartrate, also known as cream of tartar, is a byproduct of the wine industry, prepared from wine fermentation dregs. It is the calcium salt of tartaric acid, an acid predominantly found in ripe grapes. Calcium tartrate exhibits a decrease in solubility with colder temperatures, leading to the formation of whitish (or reddish in red wine) crystalline clusters as it precipitates. It is characterized by its rhomb-shaped white crystals and is known for its use as a food preservative and acidity regulator. CALCIUM TARTRATE has two asymmetric carbons, resulting in two chiral isomers and a non-chiral isomer (meso-form), with most calcium tartrate of biological origin being the chiral levorotatory (–) isomer.
Uses
Used in the Food Industry:
Calcium tartrate is used as a food preservative for its ability to maintain the freshness and quality of various food products. It also serves as an acidity regulator, helping to balance the pH levels in the food, which is essential for taste and texture.
Used in the Pharmaceutical Industry:
Calcium tartrate is used as an antacid for its ability to neutralize stomach acid, providing relief from heartburn and indigestion. Its tartaric acid content aids in reducing the acidity in the stomach, thus alleviating discomfort associated with acid reflux and other gastrointestinal issues.

Check Digit Verification of cas no
The CAS Registry Mumber 3164-34-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,6 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3164-34:
(6*3)+(5*1)+(4*6)+(3*4)+(2*3)+(1*4)=69
69 % 10 = 9
So 3164-34-9 is a valid CAS Registry Number.
