1269806-71-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1269806-71-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,9,8,0 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1269806-71:
(9*1)+(8*2)+(7*6)+(6*9)+(5*8)+(4*0)+(3*6)+(2*7)+(1*1)=194
194 % 10 = 4
So 1269806-71-4 is a valid CAS Registry Number.

Preparation of strained axially chiral (1,5)naphthalenophanes by photo-dehydro-diels-Alder reaction
Wessig, Pablo,Matthes, Annika
, p. 2642 - 2650 (2011/04/23)
The preparation of 10 (1,5)naphthalenophanes (10a-j) by photo-dehydro-Diels-Alder (PDDA) reaction is described. Owing to hindered rotation around the biaryl axis, compounds 10 are axially chiral and the separation of enantiomers by chiral HPLC was demonst
