2-Hexynedioic acid, also known as sorbic acid, is a naturally occurring organic compound with the chemical formula C6H8O4. It is a colorless crystalline solid that is soluble in water, ethanol, and ether. This six-carbon dibasic acid is characterized by the presence of a conjugated diene system and two carboxylic acid groups. 2-Hexynedioic acid is widely used as a food preservative due to its ability to inhibit the growth of mold, yeast, and bacteria. It is also found in various fruits and berries, such as mountain ash and rowan, and is used in the synthesis of vitamin C.

Check Digit Verification of cas no

The CAS Registry Mumber 3402-59-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,0 and 2 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3402-59:
(6*3)+(5*4)+(4*0)+(3*2)+(2*5)+(1*9)=63
63 % 10 = 3
So 3402-59-3 is a valid CAS Registry Number.
