32260-07-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 32260-07-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,2,6 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 32260-07:
(7*3)+(6*2)+(5*2)+(4*6)+(3*0)+(2*0)+(1*7)=74
74 % 10 = 4
So 32260-07-4 is a valid CAS Registry Number.

Synthesis of caffeic acid esters
Xia, Chun-Nian,Hu, Wei-Xiao
, p. 332 - 334 (2007/10/03)
A new method for the preparation of caffeic acid esters was investigated. Ten caffeic acid esters were prepared by condensation of protocatechualdehyde with malonic acid mono-esters in moderate yield. Malonic acid mono-esters were prepared from the corresponding malonate di-esters. The conformations of compounds are trans (E) form.
