Check Digit Verification of cas no

The CAS Registry Mumber 1258500-19-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,5,0 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1258500-19:
(9*1)+(8*2)+(7*5)+(6*8)+(5*5)+(4*0)+(3*0)+(2*1)+(1*9)=144
144 % 10 = 4
So 1258500-19-4 is a valid CAS Registry Number.

"On-water" conjugate additions of anilines

Phippen, Christopher B. W.,Beattie, James K.,McErlean, Christopher S. P.

supporting information; experimental part, p. 8234 - 8236 (2010/12/20)

The conjugate addition of anilines onto unsaturated ketones, esters and N-acylpyrroles was investigated. Based on a recently proposed explanation for the phenomenon of on-water catalysis, operationally simple and mild reaction conditions for effecting these addition reactions have been developed. The success of these additions provides further support for the acid-catalysed nature of on-water chemistry.
