Check Digit Verification of cas no

The CAS Registry Mumber 128257-86-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,2,5 and 7 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 128257-86:
(8*1)+(7*2)+(6*8)+(5*2)+(4*5)+(3*7)+(2*8)+(1*6)=143
143 % 10 = 3
So 128257-86-3 is a valid CAS Registry Number.

A NOVEL ONE-POT FLUOROALKYLVINYLATION OF THIOPHENE

Shen, Yanchang,Liao, Qimu

, p. 137 - 144 (2007/10/02)

A novel one-pot synthesis of fluoroalkylvinyl thiophenes using fluorinated β-ketophosphonium salts as a fluoroalkylvinylation reagent is described.In view of the fact that this one-pot reaction without isolation of intermediates and the total yield on 2 steps reaches 56-82percent, the present method provides a convenient direct introduction of fluoroalkylvinyl group into the thiophene.
