Check Digit Verification of cas no

The CAS Registry Mumber 63370-05-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,3,7 and 0 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 63370-05:
(7*6)+(6*3)+(5*3)+(4*7)+(3*0)+(2*0)+(1*5)=108
108 % 10 = 8
So 63370-05-8 is a valid CAS Registry Number.

Enantioselective synthesis of α-tertiary hydroxyaldehydes by palladium-catalyzed asymmetric allylic alkylation of enolates

Trost, Barry M.,Xu, Jiayi,Reichle, Markus

, p. 282 - 283 (2007/10/03)

Chiral α-tertiary hydroxyaldehydes are very versatile building blocks in synthetic chemistry. Herein, we report the first examples of a catalytic asymmetric protocol for the synthesis of such compounds from readily available α-halo or α-hydroxy ketones or enol silyl ethers with excellent yields and enantioselectivity. Its synthetic utility is demonstrated in the short, efficient formal synthesis of (S)-oxybutynin. In this process, the chiral ligand controls the regioselectivity as well as the enantioselectivity.
