7394-18-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7394-18-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,9 and 4 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7394-18:
(6*7)+(5*3)+(4*9)+(3*4)+(2*1)+(1*8)=115
115 % 10 = 5
So 7394-18-5 is a valid CAS Registry Number.

SmCl3-catalyzed C-acylation of 1,3-dicarbonyl compounds and malononitrile

Shen, Quansheng,Huang, Wen,Wang, Jialiang,Zhou, Xigeng

, p. 4491 - 4494 (2007)

(Chemical Equation Presented) A recyclable, convenient, and efficient catalytic system for C-acylation of 1,3-dicarbonyl compounds and malononitrile with acid chlorides has been developed, giving moderate to excellent yields under mild conditions. This is the first catalytic example of such reactions. In addition, by applying this protocol as the key step, 3,5-disubstituted-1H- pyrazole-4-carboxylate can easily be synthesized in high yields in a one-pot procedure.
