182185-45-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 182185-45-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,2,1,8 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 182185-45:
(8*1)+(7*8)+(6*2)+(5*1)+(4*8)+(3*5)+(2*4)+(1*5)=141
141 % 10 = 1
So 182185-45-1 is a valid CAS Registry Number.

A new route to water soluble porphyrins: Phosphonium and ammonium type cationic porphyrins and self-assembly
Jin, Ren-Hua,Aoki, Shinya,Shima, Kensuke
, p. 1939 - 1940 (1996)
From a precursor porphyrin, tetrakis(p-chloromethylphenyl)porphyrin, the novel phosphoniumyl and ammoniumyl cationic porphyrins are synthesized, and the unusual spontaneous assembly for the two cationic porphyrins is discussed.
