Check Digit Verification of cas no

The CAS Registry Mumber 936747-19-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,6,7,4 and 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 936747-19:
(8*9)+(7*3)+(6*6)+(5*7)+(4*4)+(3*7)+(2*1)+(1*9)=212
212 % 10 = 2
So 936747-19-2 is a valid CAS Registry Number.

Aqueous-mediated N-alkylation of amines

Singh, Chingakham B.,Kavala, Veerababurao,Samal, Akshaya K.,Patel, Bhisma K.

, p. 1369 - 1377 (2008/09/17)

Direct N-alkylation of primary amines to secondary/tertiary amines and of secondary amines to tertiary amines has been achieved in excellent yields by employing alkyl, benzylic and allylic halides in the presence of NaHCO 3 in an aqueous medium at an elevated temperature. Amines of different stereoelectronic nature react with ease with different halides. The selective formation of secondary amines and the formation of three different substituted tertiary amines are some of the interesting features of this methodology. Reaction in an aqueous medium, operationally convenient conditions, excellent yields and innocuous byproducts, and the absence of transition-metal catalysts, expensive bases, solid supports and the formation of undesired quaternary ammonium salts makes this method a green chemical process.
