Check Digit Verification of cas no

The CAS Registry Mumber 257296-61-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,7,2,9 and 6 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 257296-61:
(8*2)+(7*5)+(6*7)+(5*2)+(4*9)+(3*6)+(2*6)+(1*1)=170
170 % 10 = 0
So 257296-61-0 is a valid CAS Registry Number.

Stereoselective intramolecular cyclization of allyl and homoallyl benzamide via π-allylpalladium complex catalyzed by Pd(0)

Lee, Kee-Young,Kim, Yong-Hyun,Park, Min-Sung,Oh, Chang-Young,Ham, Won-Hun

, p. 9450 - 9458 (2007/10/03)

The transformation of acyclic allylic benzamides 4 and homoallylic benzamides 12 to vinyl oxazolines 3 is achieved in the presence of base by the catalysis and Pd(0) in high yield and with high diastereoselectivity. Especially, in the case of homoallylic benzamides 12, trans-oxazolines 3 are formed exclusively or predominantly over cis-oxazolines 8, irrespective of the composition of their stereoisomers. The reaction is believed to proceed via the same π-allylpalladium complex that arises from either primary or secondary allylic acetates. We applied this method to the syntheses of β- amino-α-hydroxy acids 1 and γ-amino-β-hydroxy acids 2, conveniently protected as oxazoline.
