Check Digit Verification of cas no

The CAS Registry Mumber 194411-94-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,4,4,1 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 194411-94:
(8*1)+(7*9)+(6*4)+(5*4)+(4*1)+(3*1)+(2*9)+(1*4)=144
144 % 10 = 4
So 194411-94-4 is a valid CAS Registry Number.

Synthesis of designed hetero-polytopic cryptands through Schiff base condensation

Chand, Dillip K.,Bharadwaj, Parimal K.

, p. 10517 - 10522 (1997)

Low-temperature synthesis of a number of hetero-polytopic cryptands have been achieved in good yields without employing any templating metal ion. The cryptands are designed to hold more than one metal ion in its cavity.

Synthesis of linked 1,3,5-triaroylbenzenes via enamine-directed alkyne cyclotrimerization

Pigge,Ghasedi

, p. 6545 - 6549 (2007/10/03)

Triaroylbenzenes connected via m-xylyl, p-xylyl, 4,4'-biphenyl, and 1,3,5-benzenetriyl linking units have been prepared in good yield by condensation of bis(enaminones) with aryl ethynyl ketones. The required bis(enaminones) were conveniently prepared sta
