Check Digit Verification of cas no

The CAS Registry Mumber 204522-63-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,5,2 and 2 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 204522-63:
(8*2)+(7*0)+(6*4)+(5*5)+(4*2)+(3*2)+(2*6)+(1*3)=94
94 % 10 = 4
So 204522-63-4 is a valid CAS Registry Number.

Synthesis of bis-(3,5)pyrazolophanes by sequential intermolecular-intramolecular nitrilimine cycloadditions

Broggini, Gianluigi,Garanti, Luisa,Molteni, Giorgio,Zecchi, Gaetano

, p. 2843 - 2852 (1998)

A series of bis-(3,5)pyrazolophanes of potential interest in supramolecular chemistry have been synthesized by exploiting sequential intermolecular-intramolecular cycloadditions of properly functionalised nitrilimines.
