Check Digit Verification of cas no

The CAS Registry Mumber 637759-97-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,7,7,5 and 9 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 637759-97:
(8*6)+(7*3)+(6*7)+(5*7)+(4*5)+(3*9)+(2*9)+(1*7)=218
218 % 10 = 8
So 637759-97-8 is a valid CAS Registry Number.

A new method for the synthesis of plurisubstituted pyrroles

Bashiardes, George,Safir, Imad,Barbot, Francis,Laduranty, Joelle

, p. 8417 - 8420 (2007/10/03)

A versatile method for the synthesis of pyrroles is described using an intramolecular [3+2] cycloaddition reaction. This method allows the expedient preparation of 'plurisubstituted' compounds in which functionality is incorporated by choice, using appropriate readily available starting materials. Polycyclic pyrrole derivatives as well as 2-aryl monocyclic analogues are described. Several families of compounds are synthesized by sequential transformations. The method is designed to allow the creation of libraries with increased diversity of functionality by combinatorial or parallel synthesis.
