1286734-99-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1286734-99-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,6,7,3 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1286734-99:
(9*1)+(8*2)+(7*8)+(6*6)+(5*7)+(4*3)+(3*4)+(2*9)+(1*9)=203
203 % 10 = 3
So 1286734-99-3 is a valid CAS Registry Number.

Reactive spin state dependent enantiospecific photocyclization of axially chiral α-substituted acrylanilides
Ayitou, Anoklase Jean-Luc,Sivaguru
, p. 2568 - 2570 (2011/04/26)
The enantiomeric ratio (e.r.) in the 3,4-dihydroquinolin-2-one photoproduct during 6π-photocyclization of α-substituted axially chiral ortho-tert-butyl-acrylanilides depends on the nature of the reactive spin state (singlet or triplet), where the singlet-
