426821-24-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 426821-24-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,6,8,2 and 1 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 426821-24:
(8*4)+(7*2)+(6*6)+(5*8)+(4*2)+(3*1)+(2*2)+(1*4)=141
141 % 10 = 1
So 426821-24-1 is a valid CAS Registry Number.

Catalytic one-pot synthesis of [5.5.5.6]fenestrane systems via a dicobalt octacarbonyl-catalyzed tandem cycloaddition of dienediynes
Kim, Do Han,Son, Seung Uk,Chung, Young Keun,Lee, Sueg-Geun
, p. 56 - 57 (2002)
Catalytic one-pot synthesis of fenestrane derivatives from dienediynes was developed: fenestranes were synthesized in high yields by a dicobalt octacarbonyl-catalyzed tandem cycloaddition of dienediynes.
