131318-72-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131318-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,3,1 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 131318-72:
(8*1)+(7*3)+(6*1)+(5*3)+(4*1)+(3*8)+(2*7)+(1*2)=94
94 % 10 = 4
So 131318-72-4 is a valid CAS Registry Number.

Effects of Branching of the Ester Alkyl Chain on the Mesomorphic Properties of Alkyl 4-benzoates
Matsuzaki, Hiroyuki,Matsunaga, Yoshio
, p. 2300 - 2305 (2007/10/02)
The mesomorphic properties of five homologous series of alkyl 4-benzoates, where X=CN, NO2, CH3, Cl, and CH3COO, have been studied.The ester alkyl groups employed were the following eleven types: ethyl and p
