7616-22-0 Usage
General Description
3,4-dihydro-2,7,8-trimethyl-2-(4,8,12-trimethyltridecyl)-2H-benzopyran-6-ol, also known as Alpha-tocopherol, is a type of vitamin E and a biochemically significant organic compound. It's a fat-soluble vitamin that works as an antioxidant, meaning it protects cells from damage caused by free radicals, which are harmful molecules produced when the body breaks down food or is exposed to tobacco smoke and radiation. It is naturally found in certain foods like nuts, seeds, and leafy green vegetables. Alpha-tocopherol has also been studied for its potential role in preventing illnesses like cancer and heart disease but, while it has many potential benefits, excessive consumption of it can be harmful.
Check Digit Verification of cas no
The CAS Registry Mumber 7616-22-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,1 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7616-22:
(6*7)+(5*6)+(4*1)+(3*6)+(2*2)+(1*2)=100
100 % 10 = 0
So 7616-22-0 is a valid CAS Registry Number.

FORMATION OF CHIRAL 4-CHROMANONES USING CHIRAL PYRROLIDINES IN THE PRESENCE OF ACIDS
-
Page/Page column 32; 33, (2015/01/16)
The present invention relates to a synthesis of chromanones or chromanes in a stereospecific matter in view of the 2-position in the chromanone or chromane ring. It has been found that this synthesis is particularly possible in the presence of a chiral compound of a specific type and of at least one Bransted acid or in the presence a specific chiral compound having a Bransted acid functional group in the molecule.

, (2008/06/13)
A process for the preparation of chromanyl derivatives of the formula I STR1 where R1 is hydrogen, C1 -C8 -alkyl, aryl, aralkyl, Si(R4)3, C(=O)R4 or C1 -C4 -alkoxymethyl, R2 and R3 are hydrogen or C1 -C3 -alkyl, and R4 is C1 -C8 -alkyl or aryl, which comprises decarboxylating 5-carboxychromanyl derivatives of the formula II STR2 where the substituents R1 to R3 are as defined above and 5-carboxylchromanyl derivatives of the formula II.
