35304-77-9

2(5H)-Furanone, 5-[(4-methoxyphenyl)methylene]-, (5Z)-, also known as a Z-γ-alkylidenebutenolide derivative, is a stereoselectively synthesized compound featuring a furanone core with a (Z)-configured 4-methoxyphenylmethylene substituent at the γ-position. This structure is characteristic of γ-alkylidenebutenolides, a class of compounds known for their biological activity and synthetic utility. The (Z)-stereochemistry is achieved through zeolite (H-ZSM-5)-mediated dehydration, highlighting an efficient and selective synthetic approach for such derivatives.

Check Digit Verification of cas no

The CAS Registry Mumber 35304-77-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,3,0 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 35304-77:
(7*3)+(6*5)+(5*3)+(4*0)+(3*4)+(2*7)+(1*7)=99
99 % 10 = 9
So 35304-77-9 is a valid CAS Registry Number.
