3-didehydroGA4, also known as 3-dehydro-Gibberellin A4, is a naturally occurring plant hormone that belongs to the gibberellin family. It plays a crucial role in various aspects of plant growth and development, such as stem elongation, seed germination, and flowering. 3-didehydroGA4 is structurally similar to Gibberellin A4 (GA4) but with a double bond between carbons 3 and 4, which influences its biological activity. In agricultural applications, 3-didehydroGA4 can be used to promote growth and improve crop yields, although its use is typically more focused on research to understand the mechanisms of plant growth regulation. The compound is also of interest in the study of plant responses to environmental stress and in the development of new plant growth regulators.
The CAS Registry Mumber 2619-66-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,1 and 9 respectively; the second part has 2 digits, 6 and 6 respectively. Calculate Digit Verification of CAS Registry Number 2619-66: (6*2)+(5*6)+(4*1)+(3*9)+(2*6)+(1*6)=91 91 % 10 = 1 So 2619-66-1 is a valid CAS Registry Number.
