30225-76-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 30225-76-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,2,2 and 5 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 30225-76:
(7*3)+(6*0)+(5*2)+(4*2)+(3*5)+(2*7)+(1*6)=74
74 % 10 = 4
So 30225-76-4 is a valid CAS Registry Number.

Synthesis of polyalkoxy-3-(4-methoxyphenyl)coumarins with antimitotic activity from plant allylpolyalkoxybenzenes

Tsyganov, Dmitry V.,Chernysheva, Natalia B.,Salamandra, Lev K.,Konyushkin, Leonid D.,Atamanenko, Olga P.,Semenova, Marina N.,Semenov, Victor V.

, p. 147 - 149 (2013/07/26)

Novel polyalkoxy-3-(4-methoxyphenyl)coumarins - analogues of natural antimitotic compounds - were synthesized from plant allylpolyalkoxybenzenes and tested in vivo in the phenotypic sea urchin embryo assay for antiproliferative antitubulin activity.

Enantioselective α-hydroxylation of β-keto esters catalyzed by chiral S-timolol derivatives

Cai, Yuanchun,Lian, Mingming,Li, Zhi,Meng, Qingwei

scheme or table, p. 7973 - 7977 (2012/09/21)

A screen of aryloxy aminopropanol organocatalysts derived from the β-blocker inhibitor S-timolol determined the most active catalyst of asymmetric α-hydroxylation of β-keto esters. (R)-1-(tert-butylamino)- 3-(3,4,5-trimethoxyphenoxy) propan-2-ol (3k) was the most effective derivative, enantioselectively catalyzing α-hydroxylation of β-keto esters using tert-butyl hydroperoxide as the oxidant in hexane to afford the corresponding products in excellent yield and with good enantioselectivity (up to 96% yield, 88% ee).

Selenoxides as catalysts for epoxidation and Baeyer-Villiger oxidation with hydrogen peroxide

Goodman, Margaret A.,Detty, Michael R.

, p. 1100 - 1104 (2007/10/03)

Aryl benzyl selenoxides are catalysts for the epoxidation of various olefinic substrates and the Baeyer-Villiger oxidation of aldehydes and ketones with H2O2 in CH2Cl2 at 2.5 mol% catalyst. Benzyl 3,5-bis(trifluoromethyl)phenyl selenoxide (4) was the most effective catalyst while 2-(dimethylamino)phenyl benzyl selenoxide was the least. Mono-, di-, and trisubstituted alkenes were epoxidized and adamantanone, cyclohexanone, and 3,4,5-trimethoxybenzaldehyde underwent Baeyer-Villiger oxidation using 4 and H2O2. Competition studies showed that epoxidation reactions were faster than Baeyer-Villiger oxidations although the selectivity varied only from 1.3:1 to 4.6:1. Georg Thieme Verlag Stuttgart.
