General Description
(2R)-2-hydroxy-2-(hydroxymethyl)butanedioic acid, also known as tartaric acid, is a naturally occurring organic acid found in many fruits, particularly in grapes. It is widely used as a food additive and is often added to wine to improve its taste and to stabilize its color. In addition to its culinary applications, tartaric acid is also used in the production of pharmaceuticals, cosmetics, and various other industrial products. With a molecular formula of C4H6O6, tartaric acid is a dicarboxylic acid with two stereoisomeric forms, (2R,3R)-tartaric acid and (2S,3S)-tartaric acid, both of which are important in chiral resolution and synthesis of chiral ligands. Due to its numerous applications, tartaric acid plays a significant role in various industries and is a valuable chemical compound in many aspects of modern life.
Check Digit Verification of cas no
The CAS Registry Mumber 2957-09-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,5 and 7 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2957-09:
(6*2)+(5*9)+(4*5)+(3*7)+(2*0)+(1*9)=107
107 % 10 = 7
So 2957-09-7 is a valid CAS Registry Number.
