Check Digit Verification of cas no

The CAS Registry Mumber 27032-65-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,0,3 and 2 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 27032-65:
(7*2)+(6*7)+(5*0)+(4*3)+(3*2)+(2*6)+(1*5)=91
91 % 10 = 1
So 27032-65-1 is a valid CAS Registry Number.

Synthesis of 5-chloro-7-azaindoles by Fischer reaction

Alekseyev, Roman S.,Amirova, Sabina R.,Terenin, Vladimir I.

, p. 196 - 206 (2017/05/19)

[Figure not available: see fulltext.] A simple and effective method on the basis of Fischer reaction in polyphosphoric acid is proposed for the synthesis of previously unknown heterocyclic structures that contain the 5-chloro-1H-pyrrolo[2,3-b]pyridine system. This method can be used for the synthesis of 3-substituted and 2,3-disubstituted 5-chloro-7-azaindoles with alkyl and aryl substituents.
