40662-13-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40662-13-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,6,6 and 2 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 40662-13:
(7*4)+(6*0)+(5*6)+(4*6)+(3*2)+(2*1)+(1*3)=93
93 % 10 = 3
So 40662-13-3 is a valid CAS Registry Number.

COMPOUNDS AND METHODS FOR INHIBITING CYP26 ENZYMES

-

, (2018/07/05)

Compounds described herein are inhibitors of retinoic acid inducible P450 (CYP26) enzymes, and are useful for treating diseases that are responsive to retinoids. Certain compounds have retinoid activity, are resistant to CYP26-mediated catabolism, and are used for treating diseases that are responsive to retinoids.

Aryl or heteroaryl amides of tetrahydronaphthalene, chroman, thichroman and 1,2,3,4-tetrahydroquinolinecarboxlic acids, having an electron withdrawing substituent in the aromatic or heteroaromatic moiety, having retinoid-like biological activity

-

Page column 30, (2010/11/29)

Compounds of the formula wherein the symbols have the meaning defined in the specification have retinoid-like biological activity.

Methods of treatment with compounds having RARα receptor specific or selective activity

-

, (2008/06/13)

Retinoid compounds which act specifically or selectively on RARα receptor subtypes in preference over RARβ and RARγ receptor subtypes, posses desirable pharmaceutical properties associated with retinoids, and are particularly suitable for treatment of tumors, such as acute monocytic leukemia, cervical carcinoma, myeloma, ovarian carcinomas and head and neck carcinomas, without having one or more undesirable side effects of retinoids, such as inducement of weight loss, mucocutaneous toxicity, skin irritation and teratogenecity.

Aryl or heteroaryl amides of tetrahydronaphthalene, chroman, thiochroman and 1,2,3,4,-tetrahydroquinoline carboxylic acids, having an electron withdrawing substituent in the aromatic or heteroaromatic moiety, having retinoid-like biological activity

-

, (2008/06/13)

ON THE REACTION OF SUBSTITUTED PHENOLS AND 3-METHYLBUT-2-ENOIC ACID. A COMPARATIVE STUDY

Seboek, Peter,Jekoe, Jozsef,Timar, Tibor,Jaszberenyi, Joseph Cs.

, p. 2099 - 2114 (2007/10/02)

A systematic and comparative study of the reaction of a series of substituted phenols and 3-methylbut-2-enoic acid in zinc chloride/phosphorus oxychloride and aluminum chloride/phosphorus oxychloride reveals that the formation of phenolic esters and 2,2-dimethyl-4-chromanones is strongly influenced by the substituents, their popsition on the aromatic ring of the starting phenols.Based on our study, a mixed Friedel-Crafts and Fries rearrangement mechanism is in operation in these reactions.

An efficient synthesis of dihydrocoumarins

Pickett, James E.,Van Dort, Paul C.

, p. 1161 - 1164 (2007/10/02)

Dihydrocoumarins are obtained in 40 to 60% yields in one step by heating acrylic esters with an excess of a phenol in the presence of base catalysts.

On the synthesis of substituted 2,2-dimethyl1-4-chromanones and related compounds

Seboek, Peter,Jekoe, Jozsef,Timar, Tibor,Jaszberenyi, Joseph Cs.

, p. 2791 - 2794 (2007/10/02)

A systematic study of the reaction of a series of monosubstituted phenols 3 and 3-methylbut-2-enoic acid 4 in phosphorus oxychloride/zinc chloride revealed that the formation of 4-chromanones was strongly infuenced by the substituents and their position on the aromatic ring of the starting phenols.
