765272-23-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 765272-23-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,6,5,2,7 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 765272-23:
(8*7)+(7*6)+(6*5)+(5*2)+(4*7)+(3*2)+(2*2)+(1*3)=179
179 % 10 = 9
So 765272-23-9 is a valid CAS Registry Number.

Intramolecular C-N bond addition of amides to alkynes using platinum catalyst

Shimada, Tomohiro,Nakamura, Itaru,Yamamoto, Yoshinori

, p. 10546 - 10547 (2007/10/03)

The intramolecular aminoacylation of alkynes using ortho-alkynylacetanilides proceeds in very high yields in the presence of PtCl2 catalyst. This reaction provides not only a useful procedure for synthesizing 2,3-disubstituted indoles at once from ortho-alkynylaniline derivatives, but also an interesting mechanistic aspect; the intramolecular C-N bond addition of amides to alkynes takes place readily in the presence of Pt(II) catalyst.
