Check Digit Verification of cas no

The CAS Registry Mumber 143698-00-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,6,9 and 8 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 143698-00:
(8*1)+(7*4)+(6*3)+(5*6)+(4*9)+(3*8)+(2*0)+(1*0)=144
144 % 10 = 4
So 143698-00-4 is a valid CAS Registry Number.

Lewis Acid-Promoted Reaction of β,β-Difluorinated N,O-Acetal with Silylated Nucleophiles

Tsukamoto, Takashi,Kitazume, Tomoya

, p. 1377 - 1380 (2007/10/02)

Lewis acid-promoted reaction of ethyl 3-ethoxy-2,2-difluoro-3-(dimethylamino)propionate (1) with some silylated nucleophiles afforded β,β-difluoroamines in good yields.The formation of iminium ion intermediate from 1 and BF3*OEt2 was confirmed by 19F and 13C NMR spectroscopy.
