118908-43-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118908-43-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,9,0 and 8 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 118908-43:
(8*1)+(7*1)+(6*8)+(5*9)+(4*0)+(3*8)+(2*4)+(1*3)=143
143 % 10 = 3
So 118908-43-3 is a valid CAS Registry Number.

A controlled synthesis of α-(E)-1-alkenyl ketones from β-keto benzyl esters
Hashimoto,Miyazaki,Shinoda,Ikegami
, p. 7195 - 7198 (2007/10/02)
A regio- and stereocontrolled method for the synthesis of α-(E)-1-alkenyl ketones from β-keto benzyl esters has been developed by devising the sequence of a modified Pinhey's alkenylation and a reductive removal of a benzyloxycarbonyl group with Raney nic
