342909-04-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 342909-04-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,2,9,0 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 342909-04:
(8*3)+(7*4)+(6*2)+(5*9)+(4*0)+(3*9)+(2*0)+(1*4)=140
140 % 10 = 0
So 342909-04-0 is a valid CAS Registry Number.

Geminal dicarboxylates as carbonyl surrogates for asymmetric synthesis. Part II. Scope and applications
Trost,Chul Bom Lee
, p. 3687 - 3696 (2001)
An enantioselective synthesis of allylic esters has been achieved by a novel asymmetric alkylation of allylic gem-dicarboxylates. The catalyst derived from palladium(0) and R,R-1,2-di(2′-diphenylphosphinobenzamido)cyclohexene efficiently induced the alkyl
