92669-44-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 92669-44-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,6,6 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 92669-44:
(7*9)+(6*2)+(5*6)+(4*6)+(3*9)+(2*4)+(1*4)=168
168 % 10 = 8
So 92669-44-8 is a valid CAS Registry Number.

Stereospecific Epoxidation by Air of Cholest-5-ene Derivatives catalysed by a Ruthenium Porphyrin

Marchon, Jean-Claude,Ramasseul, Renne

, p. 298 - 299 (1988)

A ruthenium porphyrin catalyses the epoxidation of several cholest-5-ene derivatives by air in high yield and with nearly complete β-stereospecificity; C-3-unprotected cholesterol is unaffected, but cholesteryl acetate gives nearly pure (>99percent) 5β,6β-epoxide.

Generation of trans-dioxoruthenium(VI) porphyrins: A photochemical approach

Zhang, Rui,Huang, Yan,Abebrese, Chris,Thompson, Helen,Vanover, Eric,Webb, Cathleen

, p. 152 - 157 (2011/11/06)

trans-Dioxoruthenium(VI) porphyrin complexes have been developed as one of the best-characterized model systems for heme-containing enzymes. Traditionally, this type of compounds can be prepared by oxidation of ruthenium(II) precursors with peroxyacids an

Ruthenium porphyrin-catalyzed aerobic oxidation of terminal aryl alkenes to aldehydes by a tandem epoxidation-isomerization pathway

Jiang, Gaoxi,Chen, Jian,Thu, Hung-Yat,Huang, Jie-Sheng,Zhu, Nianyong,Che, Chi-Ming

, p. 6638 - 6642 (2009/03/12)

(Figure Presented) Catalytic oxidation of 1-alkenes to aldehydes by an epoxidation-isomerization pathway with air or dioxygen as terminal oxidant has been realized for bulky ruthenium(VI) porphyrin catalysts. For the new, recyclable catalyst [RuVI(tmttp)O2], product yields of up to 99% and total turnover numbers of up to 1144 were obtained.
