151599-23-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 151599-23-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,5,9 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 151599-23:
(8*1)+(7*5)+(6*1)+(5*5)+(4*9)+(3*9)+(2*2)+(1*3)=144
144 % 10 = 4
So 151599-23-4 is a valid CAS Registry Number.

BENZENOID-QUINONOID TAUTOMERISM IN AZOMETHINES AND THEIR STRUCTURAL ANALOGS. XLVIII. TAUTOMERISM AND PHOTOCHROMISM OF 2-(2-HYDROXYPHENYLAMINOMETHYLENE)-3(2H)-BENZOTHIOPHENONE AND ITS ACETYL DERIVATIVES

Rybalkin, V. P.,Bren' V. A.,Minkin, V. I.,Palui, G. D.

, p. 1865 - 1869 (2007/10/02)

2-(2-Hydroxyphenylaminomethylene)-3(2H)-benzothiophenone and its diacetyl derivatives were synthesized.In solution of the monoacetyl derivative there is a tautomeric transformation in which mutual exchange by the acetyl group and a proton occurs between the N- and O'-centers, and in polar solvents (DMSO, DMFA, HMPTA) a tautomeric equilibrium is established.Two photochromic processes are observed in solutions of the diacetyl derivative under the influence of light: (E), (Z) isomerization of 2-(2-acetoxyphenylaminoethylene)-3(2H)-benzothiophenone and N -> O photoinitiated acylotropic rearrangement od 2-(N-acetyl-2-hydroxyphenylaminomethylene)-3(2H)-benzothiophenone
