Check Digit Verification of cas no

The CAS Registry Mumber 111455-27-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,4,5 and 5 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 111455-27:
(8*1)+(7*1)+(6*1)+(5*4)+(4*5)+(3*5)+(2*2)+(1*7)=87
87 % 10 = 7
So 111455-27-7 is a valid CAS Registry Number.

Synthesis of ethyl (+/-)-cis-3-(2,2-dihalogenovinyl)-2,2-dimethylcyclopropanecarboxylate

Genet, J. P.,Denis, A.,Charbonnier, F.

, p. 793 - 796 (2007/10/02)

The two (+/-) cis pyrethroid ethyl esters 2a,b have been synthesized.These esters are obtained via stereoselective ScN' cyclization of 3b to 5b.Desulfonylation of 5b with retention of configuration at low temperature (Na/Hg, -30 deg C) affords (+/-)-cis-chrysanthemonitrile 6.This nitrile is converted into cis aldehyde 7 which by Wittig reaction provides pyrethroid nitriles 8a and 8b, respectively.Finally hydrolysis of the nitrile group gives the esters 2a and 2b in 30percent overall yield from 3b.
