6939-72-6 Usage
General Description
6-oxo-6-propoxyhexanoic acid, also known as valproic acid, is a chemical compound with the molecular formula C8H16O3. It is used as an anticonvulsant and mood-stabilizing drug, primarily in the treatment of epilepsy and bipolar disorder. Valproic acid works by increasing the levels of certain neurotransmitters in the brain, which helps to control seizures and stabilize mood. It is available in various formulations, including tablets, capsules, and syrup, and is typically taken orally. Common side effects of valproic acid include dizziness, drowsiness, and stomach upset, and more serious side effects can occur with long-term use, such as liver damage and pancreatitis. Overall, valproic acid is a widely used and effective medication for the management of epilepsy and bipolar disorder.
Check Digit Verification of cas no
The CAS Registry Mumber 6939-72-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,3 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6939-72:
(6*6)+(5*9)+(4*3)+(3*9)+(2*7)+(1*2)=136
136 % 10 = 6
So 6939-72-6 is a valid CAS Registry Number.

Synergism of microwaves and immobilized enzyme catalysis in synthesis of adipic acid esters in nonaqueous media
Yadav, Ganapati D.,Lathi, Piyush S.
, p. 1699 - 1705 (2007/10/03)
Low-energy microwave irradiation leads to enhancement by a factor of up to 2.63 in comparison with conventional heating in immobilized lipase-catalyzed esterification of adipic acid with various alcohols and this effect is due to the greater frequency of collision, without any change in activation energy of the two modes of heating.
