Check Digit Verification of cas no
The CAS Registry Mumber 118346-68-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,3,4 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 118346-68:
(8*1)+(7*1)+(6*8)+(5*3)+(4*4)+(3*6)+(2*6)+(1*8)=132
132 % 10 = 2
So 118346-68-2 is a valid CAS Registry Number.

A CONVENIENT SYNTHESIS OF γ-OXO-ACRYLATES
Manfredini, S.,Simoni, D.,Zanirato, V.,Casolari, A.
, p. 3997 - 4000 (1988)
Ethyl 2,4-dioxoalkanoates react chemoselectively with pyrrolidine acetate at the more electrophilic C-2 carbonyl, producing enaminone esters which on reduction with NaCNBH3 followed by pyrrolidine elimination, were transformed into γ-oxo-acrylates.
