654673-27-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 654673-27-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,4,6,7 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 654673-27:
(8*6)+(7*5)+(6*4)+(5*6)+(4*7)+(3*3)+(2*2)+(1*7)=185
185 % 10 = 5
So 654673-27-5 is a valid CAS Registry Number.

Catalytic Asymmetric Intramolecular α-Alkylation of Aldehydes
Vignola, Nicola,List, Benjamin
, p. 450 - 451 (2007/10/03)
The development of a general catalytic asymmetric aldehyde α-alkylation reaction constitutes a major challenge in organic synthesis. Here, we report the first and successful approach toward its solution: (S)-α-methyl proline catalyzes the intramolecular a
