127039-18-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127039-18-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,0,3 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 127039-18:
(8*1)+(7*2)+(6*7)+(5*0)+(4*3)+(3*9)+(2*1)+(1*8)=113
113 % 10 = 3
So 127039-18-3 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
