87511-97-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87511-97-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,5,1 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 87511-97:
(7*8)+(6*7)+(5*5)+(4*1)+(3*1)+(2*9)+(1*7)=155
155 % 10 = 5
So 87511-97-5 is a valid CAS Registry Number.

Cobalt-catalyzed alkyne-nitrile cyclotrimerization to form pyridines in aqueous solution.
Fatland,Eaton
, p. 3131 - 3133 (2007/10/03)
A new, water-soluble cobalt(I) catalyst has been used in the aqueous, chemospecific, cyclotrimerization of one nitrile with two alkynes for the synthesis of highly functionalized pyridines. Several different functional groups are well incorporated in this
