Check Digit Verification of cas no

The CAS Registry Mumber 187592-70-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,5,9 and 2 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 187592-70:
(8*1)+(7*8)+(6*7)+(5*5)+(4*9)+(3*2)+(2*7)+(1*0)=187
187 % 10 = 7
So 187592-70-7 is a valid CAS Registry Number.

, (2008/06/13)

The compounds 3-(2,2-dichloro-3,3,3-trifluoro-1-hydroxypropyl)-2,2-dimethyl-(1R,cis)-cyclopropane carboxylic acid, cis-3-(2,2-dichloro-3,3,3-trifluoro-1-hydroxypropyl)-2,2-dimethyl-cyclopropane carboxylic acid and (1R,5S)-4-(1,1-dichloro-2,2,2-trifluoroethyl)-6,6-dimethyl-3-oxabicyclo[3.1.0]hexan-2-one occur as intermediates in a process for the preparation of insecticidally active cyclopropane carboxylate esters, said process starting from 6,6-dimethyl-4-hydroxy-3-oxabicyclo[3.1.0]hexan-2-one (Biocartol) which is reacted with the compound CF3 --CC1X2 (X=halogen) in the presence of zinc.

PRACTICAL AND STEREOCONTROLLED SYNTHESES OF BOTH (1R*,3S*)- AND (1R*,3R*)-3-(2-CHLORO-3,3,3-TRIFLUORO-1-PROPENYL)-2,2-DIMETHYLCYCLOPROPANECARBOXYLATES

The title compounds of (1R*,3S*) configuration were prepared from 3-formyl-2,2-dimethylcyclopropanecarboxylate by addition of CF3CCl2ZnCl, acetylation, and reductive β-elimination with zinc, whereas the (1R*,3R*) isomer was derived from Me2C=CHCH(OH)CCl2CF3 by diazoacetylation, Cu(II) catalyzed intramolecular cyclization, and the zinc reduction.
