26013-17-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 26013-17-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,0,1 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 26013-17:
(7*2)+(6*6)+(5*0)+(4*1)+(3*3)+(2*1)+(1*7)=72
72 % 10 = 2
So 26013-17-2 is a valid CAS Registry Number.

CLAISEN-REARRANGEMENT-MEDIATED RING CONTRACTION OF MACROCYCLIC LACTONES A NEW APPROACH TO CARBOCYCLES AND HETEROCYCLES

Funk, Raymond L.,Abelman, Matthew, M.,Munger, John D.

, p. 2831 - 2846 (2007/10/02)

Macrocyclic ketene acetals 3 undergo Claisen rearrangements smoothly and constitute a viable and general approach to hetero- or carbocyclic ring systems 4.This novel ring contraction process is subject to high internal asymmetric induction (cf. lactones 7 -> carbocycles 8) as well as relative asymmetric induction in the rearrangements of ketene acetals derived from lactones 18, 23 and 27.Finally, N-benzoylmeroquinene methyl ester (37) was prepared to demonstrate the potential of this methodology in heterocycle synthesis.
