Check Digit Verification of cas no

The CAS Registry Mumber 89876-82-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,8,7 and 6 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 89876-82:
(7*8)+(6*9)+(5*8)+(4*7)+(3*6)+(2*8)+(1*2)=214
214 % 10 = 4
So 89876-82-4 is a valid CAS Registry Number.

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
