Check Digit Verification of cas no

The CAS Registry Mumber 1426438-94-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,6,4,3 and 8 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1426438-94:
(9*1)+(8*4)+(7*2)+(6*6)+(5*4)+(4*3)+(3*8)+(2*9)+(1*4)=169
169 % 10 = 9
So 1426438-94-9 is a valid CAS Registry Number.

The dual role of ruthenium and alkali base catalysts in enabling a conceptually new shortcut to N-unsubstituted pyrroles through unmasked α-amino aldehydes

Iida, Kazuki,Miura, Takashi,Ando, Junki,Saito, Susumu

, p. 1436 - 1439 (2013)

A virtually salt-free and straightforward bimolecular assembly giving N-unsubstituted pyrroles through fully unmasked α-amino aldehydes, which was enabled by the dual effects of a catalytic ruthenium complex and an alkali metal base, is reported. Either solvent-free or acceptorless dehydrogenation facilitates high atom, step, and pot economy, which are otherwise difficult to achieve in multistep operations involving protection/deprotection.
