Check Digit Verification of cas no

The CAS Registry Mumber 120263-34-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,2,6 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 120263-34:
(8*1)+(7*2)+(6*0)+(5*2)+(4*6)+(3*3)+(2*3)+(1*4)=75
75 % 10 = 5
So 120263-34-5 is a valid CAS Registry Number.

On the Diastereoselectivity of the O-Attack of Electrophiles on Enolates from β-Ketocarboxylates

Krause, Volker,Lauer, Wolfgang,Meier, Herbert

, p. 1719 - 1724 (2007/10/02)

The O-alkylated, -silylated or -acylated derivatives 4aa-ae, 4ba, bf, 4ca, cc, cf of the pure Z or E enoles 2a-c are generated via the enolates 3a-c.In contrast to the complete regioselectivity, the Z/E diastereoselectivity depends on the substituents in
