76868-97-8 Usage
Description
Pyrenocine A is a fungal metabolite that has been found in P. terrestris and has diverse biological activities. It inhibits the asexual spore germination of the plant pathogenic fungi F. oxysporum, F. solani, M. hiemalis, and R. stolonifer (EC50s = 14, 20, 20, and 25 μg/ml, respectively). Pyrenocine A is active against B. subtilis, S. aureus, and E. coli (IC50s = 30, 45, and 200 μg/ml, respectively). It inhibits onion seedling elongation (EC50 = 4 μg/ml). Pyrenocine A is also a phytotoxin that inhibits lettuce seed germination and rice seedling elongation.
Check Digit Verification of cas no
The CAS Registry Mumber 76868-97-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,8,6 and 8 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 76868-97:
(7*7)+(6*6)+(5*8)+(4*6)+(3*8)+(2*9)+(1*7)=198
198 % 10 = 8
So 76868-97-8 is a valid CAS Registry Number.

, p. 5245 - 5250 (2007/10/02)
Starting from 5-acetyl-4-hydroxy-6-methyl-α-pyrone, three phytotoxins, pyrenocines A, B and pyrenochaetic acid A were synthesized.Retro-Diels-Alder reaction was successfully applied in the synthesis of pyrenochaetic acid A.
