The CAS Registry Mumber 1378078-21-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,8,0,7 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1378078-21:
(9*1)+(8*3)+(7*7)+(6*8)+(5*0)+(4*7)+(3*8)+(2*2)+(1*1)=187
187 % 10 = 7
So 1378078-21-7 is a valid CAS Registry Number.

Amaya, Toru,Abe, Yasushi,Inada, Yuhi,Hirao, Toshikazu

supporting information, p. 3976 - 3978 (2014/07/08)

As a self-doped conducting polyaniline bearing phosphonic acid, poly(2-methoxyaniline-5-phosphonic acid) (PMAP) was synthesized via oxidative polymerization of 2-methoxyaniline-5-phosphonic acid. The pyridinium salt of thus-obtained PMAP was water-soluble and its film exhibited conductivity.
