194494-02-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 194494-02-5 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 4 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 194494-02:
(8*1)+(7*9)+(6*4)+(5*4)+(4*9)+(3*4)+(2*0)+(1*2)=165
165 % 10 = 5
So 194494-02-5 is a valid CAS Registry Number.

Acid-catalyzed cyclization reactions of 2,2′ -bis(diarylhydroxymethyl)biphenyls to 5,5,7,7-tetraaryl-5,7-dihydrodibenzo[c,e]oxepins in the solid state

Hirano, Shinya,Toyota, Shinji,Toda, Fumio

, p. 749 - 756 (2007/10/03)

Heating of 2:1 inclusion crystals of 2,2′ -bis(hydroxydiphenylmethyl)biphenyl and formic acid in the solid state gave 5,5,7,7-tetraphenyl-5,7-dihydrodibenzo[c,e]oxepin in 89% yield. When mixtures of 2,2′-bis([bis(p-methoxyphenyl)hydroxymethyl]biphenyl and

A new type of tricolor electrochromic system based on the dynamic redox properties of hexaarylethane derivatives

Suzuki, Takanori,Nishida, Jun-Ichi,Tsuji, Takashi

, p. 2193 - 2194 (2007/10/03)

Electrochemical interconversion between 9,9,10,10-tetra-aryldihydrophenanthrene 1 and 2,2′-bis(triarylmethylium) 22+ has been proven to proceed via open form cation radical 2+ as a stable intermediate; using these three species, a no
