1434140-03-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1434140-03-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,4,1,4 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1434140-03:
(9*1)+(8*4)+(7*3)+(6*4)+(5*1)+(4*4)+(3*0)+(2*0)+(1*3)=110
110 % 10 = 0
So 1434140-03-0 is a valid CAS Registry Number.

Gold-catalyzed reactions between alkenyldiazo carbonyl species and acetals
Pagar, Vinayak Vishnu,Jadhav, Appaso M.,Liu, Rai-Shung
, p. 5711 - 5716 (2013/07/25)
In the presence of catalyst IPrAuSbF6 catalyst (IPr = 1,3-bis(diisopropylphenyl)imidazol-2-ylidene), alkenyldiazo carbonyl species react with organic acetals to give E-configured alkyl 3,5-dimethoxy-5-pent-2- enoates stereoselectively. This rea
