22905-58-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 22905-58-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,9,0 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 22905-58:
(7*2)+(6*2)+(5*9)+(4*0)+(3*5)+(2*5)+(1*8)=104
104 % 10 = 4
So 22905-58-4 is a valid CAS Registry Number.

Asymmetric Diels-Alder Reaction: Comparison of Menthoxyaluminium and Lanthanide Chiral Catalysts
Quimpere, Miguel,Jankowski, Krzysztof
, p. 676 - 677 (2007/10/02)
Some dihydropyran carboxylates synthesized via the Diels-Alder reaction with chiral catalysts display an enantiomeric excess of up to 16percent for menthoxyaluminium and up to 64percent for chiral lanthanide catalysts.
