193970-21-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 193970-21-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,9,7 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 193970-21:
(8*1)+(7*9)+(6*3)+(5*9)+(4*7)+(3*0)+(2*2)+(1*1)=167
167 % 10 = 7
So 193970-21-7 is a valid CAS Registry Number.

Rhodium-catalyzed endo -selective epoxide-opening cascades: formal synthesis of (-)-brevisin

Armbrust, Kurt W.,Beaver, Matthew G.,Jamison, Timothy F.

supporting information, p. 6941 - 6946 (2015/06/16)

[Rh(CO)2Cl]2 is as an effective catalyst for endo-selective cyclizations and cascades of epoxy-(E)-enoate alcohols, thus enabling the synthesis of oxepanes and oxepane-containing polyethers from di- and trisubstituted epoxides. Synth

Synthetic studies on maitotoxin. 2. Stereoselective synthesis of the WXYZA -ring system

Morita, Masayuki,Haketa, Tasuku,Koshino, Hiroyuki,Nakata, Tadashi

supporting information; experimental part, p. 1679 - 1682 (2009/04/12)

The stereoselective synthesis of the WXYZA -ring system of maitotoxin has been accomplished via a linear synthetic approach, in which key reactions were Sml2-induced cyclization of ss-alkoxyacrylate for the construction of the A -, Y-, and X-rings and 6-endo cyclization of hydroxy vinylepoxide for that of the Z- and W-rings.

Total synthesis of brevetoxin A: Part 2: Second generation strategy and construction of EFGH model system

Nicolaou,Wallace, Paul A.,Shi, Shuhao,Ouellette, Michael A.,Bunnage, Mark E.,Gunzner, Janet L.,Agrios, Konstantinos A.,Shi, Guo-Qiang,Gaertner, Peter,Yang, Zhen

, p. 618 - 627 (2007/10/03)

Our second generation strategy for the total synthesis of brevetoxin A involved dissection of the molecule at the ring F oxocene. Synthetically, the F ring formation was expected to occur through Wittig coupling of requisite polycyclic fragments 2 and 3,

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

Synthesis of the H ring of gambierol

Kadota, Isao,Ohno, Akio,Matsukawa, Yasuhisa,Yamamoto, Yoshinori

, p. 6373 - 6376 (2007/10/03)

Stereoselective synthesis of the H ring of gambierol was achieved from 2-deoxy-D-ribose by using the intramolecular reaction of allylstannane with aldehyde as a key step. Modified Stille coupling was successfully applied for the construction of the triene
