75227-18-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75227-18-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,2,2 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 75227-18:
(7*7)+(6*5)+(5*2)+(4*2)+(3*7)+(2*1)+(1*8)=128
128 % 10 = 8
So 75227-18-8 is a valid CAS Registry Number.

Tris(4-methoxylphenyl)phosphine-catalyzed C-C bond formation reaction: Mutual addition of aromatic aldehydes and ethyl acrylate
Teng, Jun-Jiang,Qiao, Yan-Hui,Zhang, Qing,Li, Chun-Hai,Huang, Min
, p. 848 - 858 (2013/02/25)
A highly efficient intermolecular mutual addition of aromatic aldehydes with ethyl acrylate was developed by using tris(4-methoxylphenyl)phosphine as the catalyst. The reaction corresponds to the construction of 1,4-dicarbonyl compound and allylic alcohol
