33766-43-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 33766-43-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,7,6 and 6 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 33766-43:
(7*3)+(6*3)+(5*7)+(4*6)+(3*6)+(2*4)+(1*3)=127
127 % 10 = 7
So 33766-43-7 is a valid CAS Registry Number.

FURTHER 5-METHYL COUMARINS AND OTHER CONSTITUENTS FROM THE SUBTRIBE MUTISINAE

Zredo, C.,Bohlmann, F.,King, R. M.,Robinson, H.

, p. 509 - 516 (1986)

Key Word Index-Mutisia spinosa, M. retorsa; Trichocline sinuata; Brachyclados megalanthus; Compositae; chemotaxonomy; 5-methyl coumarins; monoterpenes; geraniol and linalol derivatives; C14-acetylenic compound.The investigation of four species from the subtribe Mutisiinae afforded eight new monoterpenes, seven 5-methyl coumarins, two closely related 5-methyl chromones, two coumarane derivatives, a p-hydroxy acetophenone derivative and a new C14-acetylene.The structures were elucidated by spectroscopic methods and a few chemical transformations.The chemotaxonomy of the Mutisiinae is discussed.

Selective isomerization of epoxides to allylic alcohols catalyzed by TiO2-supported gold nanoparticles

Chemical transformation of terpenoids. VIII. Anodic oxidation of geranyl acetate

Shibuya,Murakami,Shimada,Kitagawa

, p. 1302 - 1304 (2007/10/02)

Constant-current electrolysis of geranyl acetate (2) in CH3CN-H2O afforded eight oxidation products (3-10) which were presumed to be formed through initial oxidation of the double bond at C6-C7. Based on the results of electrolysis of 2 in CH3CN-H218O we have found that the oxygen atom(s) in the products (3-10) is(are) derived from water used as the reaction medium.
