118934-11-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118934-11-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,9,3 and 4 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 118934-11:
(8*1)+(7*1)+(6*8)+(5*9)+(4*3)+(3*4)+(2*1)+(1*1)=135
135 % 10 = 5
So 118934-11-5 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
