Check Digit Verification of cas no

The CAS Registry Mumber 143017-69-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,0,1 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 143017-69:
(8*1)+(7*4)+(6*3)+(5*0)+(4*1)+(3*7)+(2*6)+(1*9)=100
100 % 10 = 0
So 143017-69-0 is a valid CAS Registry Number.

CONTRIBUTIONS TO THE CHEMISTRY OF ORGANIC SILICON-NITROGEN-COMPOUNDS, I. SYNTHESIS OF N,N-BIS-(TRIMETHYLSILYL)AMINES

Schorr, Manfred,Schmitt, Wilfried

, p. 25 - 36 (2007/10/02)

The preparation of N,N-bis-(trimethylsilyl)amines 1 has been investigated.Three convenient methods are reported: A, Transfer of (catalytically) activated Tms-groups to amines starting from N-silylated carbonamides, B, silylation of amines with trimethylsilylchloride 5/NEt3 in the presence of TiCl4, C, silylation of primary amines 4 or mono-(trimethylsilyl)amines 16 with CF3SO3 Tms/NEt3 or TmsI/NEt3.Methods A and B are limited to the silylation of (ar)alkylamines which have no branched α-position. Key words: N,N-bis-(trimethylsilyl)amines; N,N-bis-silylamines; N-silylcarbonamides.
