688034-91-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 688034-91-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,8,0,3 and 4 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 688034-91:
(8*6)+(7*8)+(6*8)+(5*0)+(4*3)+(3*4)+(2*9)+(1*1)=195
195 % 10 = 5
So 688034-91-5 is a valid CAS Registry Number.

Carbohydrate/DBU Cocatalyzed Alkene Diboration: Mechanistic Insight Provides Enhanced Catalytic Efficiency and Substrate Scope

Yan, Lu,Meng, Yan,Haeffner, Fredrik,Leon, Robert M.,Crockett, Michael P.,Morken, James P.

supporting information, p. 3663 - 3673 (2018/03/21)

A mechanistic investigation of the carbohydrate/DBU cocatalyzed enantioselective diboration of alkenes is presented. These studies provide an understanding of the origin of stereoselectivity and also reveal a strategy for enhancing reactivity and broadening the substrate scope.

Stereoselective total synthesis of ophiocerin C through two different approaches

Srilatha, Malampati,Das, Biswanath

, p. 1577 - 1582 (2015/01/09)

Stereoselective total synthesis of ophiocerin C has been accomplished through two different approaches starting separately from acetaldehyde and from (R)-propylene oxide, and Sharpless asymmetric dihydroxylation has been employed as the key step in both a

A practical, stereospecific route to 18-, 19-, and 20-hydroxyeicosa-5(Z), 8(Z),11(Z),14(Z)-tetraenoic acids (18-, 19-, and 20-HETEs)

Gopal, V. Raj,Jagadeesh,Reddy, Y. Krishna,Bandyopadhyay,Capdevila, Jorge H.,Falck

, p. 2563 - 2565 (2007/10/03)

Suzuki-Miyaura cross-coupling of cis-vinylbromide 6, obtained in three steps from diol 4, with functionalized boranes provides a practical, stereospecific route to the title CYP P450 eicosanoids.
