Check Digit Verification of cas no

The CAS Registry Mumber 76943-40-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,9,4 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 76943-40:
(7*7)+(6*6)+(5*9)+(4*4)+(3*3)+(2*4)+(1*0)=163
163 % 10 = 3
So 76943-40-3 is a valid CAS Registry Number.

Rearrangement of 2-Ethynylpyridinium N-Imides to Pyrazolopyridines

Tsuchiya, Takashi,Sashida, Haruki

, p. 1109 - 1110 (1980)

Pyrazolopyridines (6) are obtained from the N-amino-2-ethynylpyridinium salts (5) on treatment with base.

Thermal Rearrangements of Cyclic Amine Ylides. III. Intramolecular Cyclization of 2-Ethynylpyridine N-Imides to 3-Azaindolizine Derivatives

Tsuchiya, Takashi,Sashida, Haruki,Konoshita, Ari

, p. 4568 - 4572 (2007/10/02)

Treatment of the N-aminopyridinium salts (5a-e) prepared from 2-ethynylpyridines (4) with potassium carbonate resulted in an intramolecular cyclization to give the corresponding 3-azaindolizines (6) (pyrazolopyridines), presumably via the ionic in
