194492-72-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 194492-72-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,4,4,9 and 2 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 194492-72:
(8*1)+(7*9)+(6*4)+(5*4)+(4*9)+(3*2)+(2*7)+(1*2)=173
173 % 10 = 3
So 194492-72-3 is a valid CAS Registry Number.

Chemo-enzymatic synthesis of amino acid-based surfactants
Valivety,Jauregi,Gill,Vulfson
, p. 879 - 886 (2007/10/03)
The application of lipases to the synthesis of amino acid-based surfactants was investigated. Low yields (2-9%) were obtained in the acylation of free amino acids, such as L-serine and L-lysine, as well as their ethyl esters and amides with fatty acids, o
