Vernolepin p-Brombenzolsulfonat, also known as Vernolepin p-Toluenesulfonate, is a chemical compound derived from vernolepin, a naturally occurring sesquiterpene lactone found in the Vernonia plant. Vernolepin p-Brombenzolsulfonat is characterized by the addition of a p-bromobenzenesulfonate group to the vernolepin molecule, which can enhance its reactivity and solubility properties. It is often used in organic synthesis and chemical research, particularly in the study of sesquiterpene lactones and their potential applications in pharmaceuticals and agrochemicals. The compound's structure allows for further functionalization and exploration of its chemical properties, making it a valuable tool in the field of natural product chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 20107-25-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,1,0 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 20107-25:
(7*2)+(6*0)+(5*1)+(4*0)+(3*7)+(2*2)+(1*5)=49
49 % 10 = 9
So 20107-25-9 is a valid CAS Registry Number.
