269-43-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 269-43-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,6 and 9 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 269-43:
(5*2)+(4*6)+(3*9)+(2*4)+(1*3)=72
72 % 10 = 2
So 269-43-2 is a valid CAS Registry Number.

Gold-catalyzed [4+3]-annulation of oxabicyclic benzenes with 2-substituted allylsilanes through tandem allylation and cyclization

Hsu, Yu-Chia,Datta, Swarup,Ting, Chun-Ming,Liu, Rai-Shung

, p. 521 - 524 (2008/09/19)

This work reports new gold-catalyzed [4 + 3]-annulations of oxacyclic benzenes with 2-substituted allylsilanes through tandem allylation and cyclization; on the basis of experimental observations, we propose a mechanism involving the opening of the oxacyclic ring by a PPh3Au +assisted SN2-attack of allylsilanes.
