170502-12-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 170502-12-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,0,5,0 and 2 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 170502-12:
(8*1)+(7*7)+(6*0)+(5*5)+(4*0)+(3*2)+(2*1)+(1*2)=92
92 % 10 = 2
So 170502-12-2 is a valid CAS Registry Number.

Asymmetric Friedel-Crafts alkylation using chiral α-acyl-α-chloromethylsulphides

Madan, Sachin,Sharma,Bari

, p. 2267 - 2270 (2000)

Lewis acid catalysed stereoselective Friedel-Crafts alkylation of aromatic compounds with α-(-)-menthyloxycarbonyl-α-(phenylthio)methyl chloride and α-(-)-8-phenylmenthyloxycarbonyl-α-(phenylthio)methyl chloride is described. Copyright (C) 2000 Elsevier Science Ltd.

Electrolytic partial fluorination of organic compounds. Part 15. Stereochemical study of the anodic monofluorination of α-phenylsulfenyl acetates

Narizuka, Satoru,Koshiyama, Hiroshi,Konno, Akinori,Fuchigami, Toshio

, p. 121 - 128 (2007/10/02)

The diastereoselective anodic fluorination of α-phenylsulfenyl esters by intramolecular asymmetry-induction has been studied using chiral auxiliaries such as phenethyl, bornyl, isobornyl, menthyl and 8-phenylmenthyl groups.Of these chiral auxiliaries, the 8-phenylmenthyl group gave the best diastereoselectivity.The diastereoselectivity was also affected by supporting electrolytes and it was found that Et4NF*3HF showed better selectivity in comparison to Et3N*3HF and Et3N*2HF. - Keywords: Electrolytic partial fluorination; Organic compounds; α-phenylsulfenyl acetates; Diastereoselectivity; Chiral fluorocompounds
