Check Digit Verification of cas no

The CAS Registry Mumber 1586805-88-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,8,6,8,0 and 5 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1586805-88:
(9*1)+(8*5)+(7*8)+(6*6)+(5*8)+(4*0)+(3*5)+(2*8)+(1*8)=220
220 % 10 = 0
So 1586805-88-0 is a valid CAS Registry Number.

Recyclable, graphite-catalyzed, four-component synthesis of functionalized pyrroles

Nandeesh,Raghavendra,Revanna,Vijay, T.A. Jenifer,Rangappa,Mantelingu

supporting information, p. 1103 - 1110 (2014/04/03)

A facile, convenient, and multicomponent coupling strategy for the synthesis of highly functionalized pyrroles is developed using graphite as a catalyst, but devoid of moisture-sensitive metal catalysts and corrosive acidic reagents. This method involves four-component coupling reactions of ethyl acetoacetate compound or diethyl acetylene dicarboxylate, amines, aromatic aldehydes, and nitromethane without an inert atmosphere. This approach provides easy access to highly substituted pyrroles in good yields via one-pot tandem reaction. The method is very simple, straightforward, and environmentally friendly compared to the existing methods.
