Check Digit Verification of cas no

The CAS Registry Mumber 1198092-13-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,8,0,9 and 2 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1198092-13:
(9*1)+(8*1)+(7*9)+(6*8)+(5*0)+(4*9)+(3*2)+(2*1)+(1*3)=175
175 % 10 = 5
So 1198092-13-5 is a valid CAS Registry Number.

Highly selective N-Alkylation of amines promoted on silica: An efficient and recyclable surface

Basu, Basudeb,Paul, Susmita,Nanda, Ashis K.

, p. 1115 - 1120 (2009)

N-Alkylation of amines suffers from competing over alkylations. At the same time, use of strong base and other harsh conditions greatly limits providing a practical, generalized and selective procedure. Activated silica gel has been found to promote N-alkylations of amines. Here, we studied N-alkylation of amines with various types of alkyl halides, which finally constitute practical, highly selective and eco-friendly conditions for mono- or bis-alkylated amines at ambient temperature with recyclability of silica.
