Check Digit Verification of cas no

The CAS Registry Mumber 397870-23-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,7,8,7 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 397870-23:
(8*3)+(7*9)+(6*7)+(5*8)+(4*7)+(3*0)+(2*2)+(1*3)=204
204 % 10 = 4
So 397870-23-4 is a valid CAS Registry Number.

Synthesis of 1-azaspirocycles via Lewis acid-mediated spirocyclization of cyclic N-acyl-N,O-acetals

Ito,Yamazaki,Kibayashi

, p. 1506 - 1510 (2007/10/03)

A new approach to 1-azaspirocycles has been developed starting from cyclic N-acyl-N,O-acetals. This sequence involves olefin-iminium cyclization mediated by Lewis acids leading to the spirocyclization products including the chlorinated products and the olefinic products. Mixtures of these products underwent catalytic hydrogenation and reductive dechlorination to produce the 1-azaspirans.
