Check Digit Verification of cas no

The CAS Registry Mumber 1245917-30-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,5,9,1 and 7 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1245917-30:
(9*1)+(8*2)+(7*4)+(6*5)+(5*9)+(4*1)+(3*7)+(2*3)+(1*0)=159
159 % 10 = 9
So 1245917-30-9 is a valid CAS Registry Number.

Palladium-catalyzed enantioselective ene and aldol reactions with isatins, keto esters, and diketones: Reliable approach to chiral tertiary alcohols

Aikawa, Kohsuke,Mimura, Shunsuke,Numata, Yukinobu,Mikami, Koichi

, p. 62 - 65 (2011)

Chiral dicationic Pd-complex-catalyzed enantioselective ene and aldol reactions with various isatin derivatives are shown to produce the corresponding 3-hydroxy-2-oxindole products in good yields with high enantioselectivities. These catalytic processes are effective not only with isatins but also with keto esters and diketones derivatives. Even with unprotected isatin, high yields and enantioselectivities were obtained to produce convolutamydine A as a naturally occurring compound. Sequentially, α-oxidation by m-CPBA and α-fluorination by selectfluor of the ene product could be achieved to give the corresponding α-hydroxy and α-fluoro ketones, respectively. Chiral dicationic Pd complex catalyzed enantioselective ene and aldol reactions with various isatin derivatives gave the corresponding 3-hydroxy-2-oxindole products bearing tertiary alcohols in high yields and enantioselectivities.
