Check Digit Verification of cas no

The CAS Registry Mumber 423158-72-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,3,1,5 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 423158-72:
(8*4)+(7*2)+(6*3)+(5*1)+(4*5)+(3*8)+(2*7)+(1*2)=129
129 % 10 = 9
So 423158-72-9 is a valid CAS Registry Number.

Unexpected rearrangement in the Heck cyclization of positional isomers of chiral 2,3-disubstituted perhydro-1,3-benzoxazines

Pedrosa, Rafael,Andrés, Celia,Iglesias, Jesús M.

, p. 259 - 262 (2007/10/03)

The intramolecular Heck cyclization on 2,3-disubstituted perhydro-1,3-benzoxazines, derived from (-)-8-amino menthol, easily proceeds at reflux of acetonitrile or DMF. The behavior of positional isomers was quite different. Reaction of 2-aryl-3-allyl perh
