1239969-17-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1239969-17-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,9,6 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1239969-17:
(9*1)+(8*2)+(7*3)+(6*9)+(5*9)+(4*6)+(3*9)+(2*1)+(1*7)=205
205 % 10 = 5
So 1239969-17-5 is a valid CAS Registry Number.

Selective propargylation of AZO compounds with barium reagents

Yanagisawa, Akira,Koide, Takanori,Yoshida, Kazuhiro

, p. 1515 - 1518 (2010)

A Barbier-type propargylation of azo compounds with γ- trialkylsilylated propargylic bromides has been achieved using reactive barium as a low-valent metal in THF. Corresponding propargylated hydrazines (α-adducts) were exclusively formed not only from azobenzenes (diaryldiazenes) but also from dialkyl azodicarboxylates. This method is also applicable to -alkylated or γ-phenylated propargylic bromides, providing the desired propargylated products only. Georg Thieme Verlag Stuttgart New York.
