Check Digit Verification of cas no

The CAS Registry Mumber 1234693-07-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,4,6,9 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1234693-07:
(9*1)+(8*2)+(7*3)+(6*4)+(5*6)+(4*9)+(3*3)+(2*0)+(1*7)=152
152 % 10 = 2
So 1234693-07-2 is a valid CAS Registry Number.

Stereoselective synthesis of β-proline derivatives from allylamines via domino hydroformylation/wittig olefination and aza-michael addition

Farwick, Andreas,Heimchen, Guenter

experimental part, p. 1023 - 1032 (2010/06/17)

Under appropriate reaction conditions, a domino hydroformylation/Wittig olefination can be accomplished with derivatives of allylamines and stabilized Wittig ylides. A further highly diastereoselective aza-Michael reaction yields β-proline derivatives. These are, for example, useful as building blocks for alkaloid syntheses.
