Check Digit Verification of cas no

The CAS Registry Mumber 351186-81-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,1,1,8 and 6 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 351186-81:
(8*3)+(7*5)+(6*1)+(5*1)+(4*8)+(3*6)+(2*8)+(1*1)=137
137 % 10 = 7
So 351186-81-7 is a valid CAS Registry Number.

Total synthesis of (-)-brevenal: A streamlined strategy for practical synthesis of polycyclic ethers

Ebine, Makoto,Fuwa, Haruhiko,Sasaki, Makoto

, p. 13754 - 13761 (2012/01/06)

We describe a streamlined strategy for the practical synthesis of trans-fused polycyclic ethers and its application to a concise total synthesis of (-)-brevenal, a new pentacyclic polyether natural product with intriguing biological activities. The B-, D-, and E-rings were constructed by TEMPO/PhI(OAc)2-mediated oxidative lactonization of the corresponding 1,6-diols, with minimal need for manipulation of oxygen functionalities. The B- and E-ring lactones were appropriately functionalized by Suzuki-Miyaura coupling of lactone-derived enol phosphates and subsequent stereoselective hydroboration. The A-ring was formed by our mixed thioacetalization methodology. The AB- and DE-ring fragments were assembled through Suzuki-Miyaura coupling, and the C-ring was forged in the same manner as that for the A-ring. More than two grams of the pentacyclic polyether core of (-)-brevenal have been synthesized by the synthetic route developed in this study.

A general strategy for the convergent synthesis of fused polycyclic ethers via B-alkyl Suzuki coupling: Synthesis of the ABCD ring fragment of ciguatoxins

Sasaki, Makoto,Ishikawa, Makoto,Fuwa, Haruhiko,Tachibana, Kazuo

, p. 1889 - 1911 (2007/10/03)

A new method for convergent coupling of fused polycyclic ethers has been developed, which relies on B-alkyl Suzuki crosscoupling of lactone-derived enol triflates or phosphates. The strategy was successfully applied to a convergent synthesis of the ABCD r

A general method for convergent synthesis of polycyclic ethers based on Suzuki cross-coupling: Concise synthesis of the ABCD ring system of ciguatoxin

Sasaki, Makoto,Fuwa, Haruhiko,Ishikawa, Makoto,Tachibana, Kazuo

, p. 1075 - 1077 (2008/02/09)

(matrix presented) A general method for convergent assembly of polyether structure has been developed based on palladium(0)-mediated Suzuki cross-coupling reaction of alkylboranes with cyclic ketene acetal phosphates. The present method allowed for coupli
