Check Digit Verification of cas no
The CAS Registry Mumber 412313-45-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,1,2,3,1 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 412313-45:
(8*4)+(7*1)+(6*2)+(5*3)+(4*1)+(3*3)+(2*4)+(1*5)=92
92 % 10 = 2
So 412313-45-2 is a valid CAS Registry Number.

TRIMETHYLCHOLOROSILANE INDUCED RING OPENING OF 2-ALKYLOXAZOLIDINES TO ENAMINE DERIVATIVES
Ito, Yoshihiko,Sawamura, Masaya,Kominami, Kazuhiko,Saegusa, Takeo
, p. 5303 - 5306 (2007/10/02)
2-Alkyloxazolidines (5) were ring-opened by trimethylchlorosilane with N,N-diisopropylamine to give N--enamines (6).A MgCl2 promoted Michael reaction of chiral enamines thus prepared was achieved with asymmetric induction.
