71404-68-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 71404-68-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,4,0 and 4 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 71404-68:
(7*7)+(6*1)+(5*4)+(4*0)+(3*4)+(2*6)+(1*8)=107
107 % 10 = 7
So 71404-68-7 is a valid CAS Registry Number.

INTRAMOLECULAR ARYLSULPHOETHERIFICATION AND LACTONIZATION OF UNSATURATED ALCOHOLS AND CARBOXYLIC ACIDS INITIATED BY ANODIC OXIDATION OF DISULPHIDES

Toeteberg-Kaulen, Sabine,Steckhan, Eberhard

, p. 4389 - 4398 (2007/10/02)

The intramolecular sulphoetherification respectively sulpholactonization of alkenols and alkenoic acids can be initiated by addition of electrochemically generated sulphenyl cations starting from disulphides.The reaction can either be initiated by indirect electrochemical oxidation of diphenyldisulphide using bromide as redox catalyst or preferably by direct anodic oxidation of bis(4-methoxyphenyl)disulphide. 5- and 6-membered thioaryl substituted ethers and lactones thus may be generated starting preferably from mono or disubstituted alkenols and alkenoic acids.The reaction occurs as a trans-addition to the double bond while for endocyclic double bonds the new ring is cis-annelated.
