Calculate Digit Verification of CAS Registry Number 157493-75:
(8*1)+(7*5)+(6*7)+(5*4)+(4*9)+(3*3)+(2*7)+(1*5)=169
169 % 10 = 9
So 157493-75-9 is a valid CAS Registry Number.

SYNTHESIS OF CYCLOHEXA-2,5-DIENONEQUINAZOLINE DERIVATIVES AND THEIR PHOTO- AND THERMOCHROMIC PROPERTIES

Komissarov, V. N.,Gruzdeva, E. N.,Kharlanov, V. A.,Kogan, V. A.,Minkin, V. I.

, p. 1688 - 1691 (2007/10/02)

The reaction of 5-amino-4-arylamino-2,8-dimethylquinolines with 2,6-di-tert-butyl-1,4-benzoquinone leads to substituted 2,3-dihydro-2',6'-di-tert-butylquinazoline-2-spiro-4'-cyclohexa-2',5'-dien-1'-ones, which exhibit photo- and thermochromic characteristics in solutions on account of their transformation into the corresponding colored N-(4-arylamino-5-quinolyl)-2,6-di-tert-butyl-4-imino-2,5-cyclohexadien-1-ones.
