1-oxo-GA5, also known as abscisic acid (ABA), is a plant hormone that plays a crucial role in various physiological processes, including seed dormancy, stomatal closure, and stress responses. It is a sesquiterpene compound derived from the isoprenoid biosynthetic pathway and is characterized by a cyclohexenone ring structure. ABA is synthesized in response to environmental stressors such as drought, high salinity, and cold temperatures, and it helps plants to adapt to these conditions by regulating gene expression, hormone signaling, and cellular processes. The chemical structure of 1-oxo-GA5 consists of a 15-carbon skeleton with a conjugated carbonyl group, which is essential for its biological activity.
The CAS Registry Mumber 83455-32-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,4,5 and 5 respectively; the second part has 2 digits, 3 and 2 respectively. Calculate Digit Verification of CAS Registry Number 83455-32: (7*8)+(6*3)+(5*4)+(4*5)+(3*5)+(2*3)+(1*2)=137 137 % 10 = 7 So 83455-32-7 is a valid CAS Registry Number.
