Check Digit Verification of cas no

The CAS Registry Mumber 1315610-76-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,5,6,1 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1315610-76:
(9*1)+(8*3)+(7*1)+(6*5)+(5*6)+(4*1)+(3*0)+(2*7)+(1*6)=124
124 % 10 = 4
So 1315610-76-4 is a valid CAS Registry Number.

Synthesis and mesomorphic properties of a series of phenyl 6-(4-alkoxyphenyl)nicotinates

Chia, Win-Long,Tsai, Cheng-Yao

, p. 1057 - 1065 (2011/06/19)

A new homologous series of phenyl 6-(4-alkoxyphenyl)nicotinates (nOPNicP, n=3-7) was synthesized. The entire synthetic procedure was completed in a short two-step process. Very good two-step overall yields of 70-80% were obtained and high α-regioselective addition of Grignard reagents to 1-acylnicotinium salts was observed while preparing this series of liquid crystals. Spectral analyses were in accordance with the expected structures. Their thermotropic behaviours were studied using polarizing optical microscopy and further confirmed by differential scanning calorimetry. Smectic A phase was found to be the only mesophase in this series of compounds. The Japan Institute of Heterocyclic Chemistry.
