Check Digit Verification of cas no

The CAS Registry Mumber 1330557-45-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,0,5,5 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1330557-45:
(9*1)+(8*3)+(7*3)+(6*0)+(5*5)+(4*5)+(3*7)+(2*4)+(1*5)=133
133 % 10 = 3
So 1330557-45-3 is a valid CAS Registry Number.

Palladium-catalysed amination of bromofluorans and an investigation of their thermochromic behaviour

Azizian, Farid,Field, Amanda J.,Griffiths, John,Heron, B. Mark

, p. 524 - 530 (2012/02/02)

The palladium-catalysed amination of readily accessible bromofluorans and bromobenzo[a]fluorans has been accomplished with a series of anilines and morpholine. The resulting aminofluorans generated intense black shades upon formulation in methyl stearate containing bisphenol A. The route provides an alternative approach to various amino substituted fluorans without the need of a series of individual diphenylamine intermediates.
