16146-60-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 16146-60-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,1,4 and 6 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 16146-60:
(7*1)+(6*6)+(5*1)+(4*4)+(3*6)+(2*6)+(1*0)=94
94 % 10 = 4
So 16146-60-4 is a valid CAS Registry Number.

Synthesis of α-tocopherol analogs with unsaturated side chain and their transformation into the corresponding chromans with ω-functionalized side chain

Odinokov,Spivak,Emelianova,Kutepov,Khalilov

, p. 2227 - 2230 (2001)

α-Tocopherol analogs with double bond-containing side chains were synthesized by condensation of trimethylhydroquinone with optically active (3R/S,4S)-3,4,8-trimethylnona1,7-dien-3-ol and linalool in the presence of the zeolite-containing Tseokar-10 aluminosilicate. Ozonolysis of these compounds gave the corresponding chromans with ω-formyl or (after hydride reduction) ω-hydroxyl groups in the side chain.

Synthesis of α-tocopherol and naphthotocopherol analogs with a carboxyl group in the side chain

Spivak,Knyshenko,Mallyabaeva,Odinokov

, p. 306 - 311 (2007/10/03)

On the basis of ozonolysis of short-chain α-tocopherol and naphthotocopherol analogs with a terminal isopropylidene group in the side chain, a general approach to the synthesis of 6-hydroxy-2,5,7,8- tetrtamethylchroman-2-yl-and 6-hydroxy-2,5-dimethyl-3,4-
