808750-22-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 808750-22-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,8,7,5 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 808750-22:
(8*8)+(7*0)+(6*8)+(5*7)+(4*5)+(3*0)+(2*2)+(1*2)=173
173 % 10 = 3
So 808750-22-3 is a valid CAS Registry Number.

Palladium/Norbornene-Catalyzed Indenone Synthesis from Simple Aryl Iodides: Concise Syntheses of Pauciflorol F and Acredinone A

Liu, Feipeng,Dong, Zhe,Wang, Jianchun,Dong, Guangbin

supporting information, p. 2144 - 2148 (2019/01/24)

To show the synthetic utility of palladium/norbornene (Pd/NBE) cooperative catalysis, here we report concise syntheses of indenone-based natural products, pauciflorol F and acredinone A, which are enabled by direct annulation between aryl iodides and unsa

Synthetic studies on Ecteinascidin-743: synthesis of building blocks through Sharpless asymmetric dihydroxylation and aza-Michael reactions

Chandrasekhar,Reddy, N. Ramakrishna,Rao, Y. Srinivasa

, p. 12098 - 12107 (2007/10/03)

A practical and an efficient synthesis of three building blocks of tetrahydroisoquinoline alkaloid Ecteinascidin-743 was accomplished, starting from readily available piperonal, 2-methyl anisole, and veratraldehyde. A combination of Vilsmeier-Haack reaction and Sharpless asymmetric dihydroxylation was employed for the synthesis of building blocks A and B whereas a Heck reaction in PEG-2000 and aza-Michael reactions were employed for the synthesis of building block C.
