1-oxo-GA20, also known as 1-oxo-gibberellin A20, is a naturally occurring plant hormone derivative that plays a crucial role in regulating plant growth and development. It is a member of the gibberellin family, which consists of a group of tetracyclic diterpenoid compounds. 1-oxo-GA20 is synthesized from GA20 through the action of the enzyme gibberellin 20-oxidase, which introduces a 3-keto group into the molecule. This modification is essential for the biological activity of gibberellins, as it allows them to interact with their receptors and initiate signaling pathways that control various aspects of plant growth, such as stem elongation, seed germination, and flowering. The balance of gibberellins, including 1-oxo-GA20, is critical for maintaining proper plant development and responding to environmental cues.
The CAS Registry Mumber 83455-33-8 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 3 respectively. Calculate Digit Verification of CAS Registry Number 83455-33: (7*8)+(6*3)+(5*4)+(4*5)+(3*5)+(2*3)+(1*3)=138 138 % 10 = 8 So 83455-33-8 is a valid CAS Registry Number.
