Check Digit Verification of cas no
The CAS Registry Mumber 71648-20-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,6,4 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 71648-20:
(7*7)+(6*1)+(5*6)+(4*4)+(3*8)+(2*2)+(1*0)=129
129 % 10 = 9
So 71648-20-9 is a valid CAS Registry Number.

Highly Selective Ring-opening of 1,3,3-Trohalogenoepoxycyclohexanes by Boron Trihalides; Methodology for Determination of the Regioselectivity in the Cyclization of 2,2,6,6-Tertrahalogenocyclohexanols

Reaction of 1,3,3-trihalogeno-7-oxabicycloheptanes with boron trihalides (F, Cl, Br) resulted in the regio- and stereo-selective formation in high yield of the corresponding tetrahalohydrins.In these reactions the hypervalent halogenoborate species are responsible for the selective halogenation of the epoxides by cis opening.A methodology is given to predict the regioselectivity in the epoxidic cyclization of 2,2,6,6-tetrahalogenocyclohexanols.These processes allowed the preparation of all the isomers of 1,3,3-trihalogeno-7-oxabicycloheptanes or 2,2,6,6-tetrahalogenocyclohexanols (X = Cl, F), very useful intermediates.
