The CAS Registry Mumber 1629189-68-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,9,1,8 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1629189-68:
(9*1)+(8*6)+(7*2)+(6*9)+(5*1)+(4*8)+(3*9)+(2*6)+(1*8)=209
209 % 10 = 9
So 1629189-68-9 is a valid CAS Registry Number.

A simple and convenient method for the synthesis of N, N-diaryl tertiary amines

Wekesa, Francis S.,Phadke, Neha,Jahier, Claire,Cordes, David B.,Findlater, Michael

, p. 1046 - 1051 (2014)

Direct preparation of tertiary amines in which two substituents are aromatic is described. In the presence of either the inorganic base sodium tert-butoxide or the sterically hindered organic base diisopropylethylamine, the alkylation of secondary diarylamines is achieved smoothly. In contrast to methods previously reported in the literature, this procedure is high-yielding and does not require the use of transition-metal catalysts or functional-group-intolerant hydride reductants.
