Humulinone, also known as dihydrophaseic acid, is a naturally occurring chemical compound found in the seeds of the Phaseolus vulgaris plant, commonly known as the common bean. It is a triterpene, a type of organic compound derived from the isoprene unit, and is structurally similar to the aglycone of the saponin glycosides. Humulinone has been studied for its potential antifungal properties, as it has been shown to inhibit the growth of certain fungi. Additionally, it has been identified as a precursor in the biosynthesis of phaseollin, a phytoalexin produced by beans in response to infection by pathogens. The compound's role in plant defense mechanisms and its potential applications in agriculture and medicine are areas of ongoing research.
The CAS Registry Mumber 981-03-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,8 and 1 respectively; the second part has 2 digits, 0 and 3 respectively. Calculate Digit Verification of CAS Registry Number 981-03: (5*9)+(4*8)+(3*1)+(2*0)+(1*3)=83 83 % 10 = 3 So 981-03-3 is a valid CAS Registry Number.
