Check Digit Verification of cas no

The CAS Registry Mumber 90909-78-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,9,0 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 90909-78:
(7*9)+(6*0)+(5*9)+(4*0)+(3*9)+(2*7)+(1*8)=157
157 % 10 = 7
So 90909-78-7 is a valid CAS Registry Number.

On the Reaction of 2-Pyrrolecarbaldehyde with Hetero-substituted Ethenes

Flitsch, Wilhelm,Lubisch, Wilfried

, p. 1424 - 1435 (2007/10/02)

3H-Pyrrolizines 1 have been obtained from reactions of 2-pyrrolecarbaldehyde with ethenylphosphonates 2 and the phosphane oxide 5, respectively, the ratio of products depending on the structure of the educts.On varying the reaction conditions a controlled synthesis of both isomers 1e/f was achieved.Pyrrolizines, formed in a reaction of 2-pyrrolecarbaldehyde with ethenyl phenyl sulfone (3), could not be isolated since the reaction proceeded to give more complex pyrrolizine derivatives and the cyclazine 11.A mechanism is proposed for this multistep reaction.N-Alkylatio n of 2-pyrrolecarbaldehyde with dihaloalkanes has been carried out using phase transfer catalysis.
