102245-22-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 102245-22-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,2,4 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 102245-22:
(8*1)+(7*0)+(6*2)+(5*2)+(4*4)+(3*5)+(2*2)+(1*2)=67
67 % 10 = 7
So 102245-22-7 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.
