Check Digit Verification of cas no

The CAS Registry Mumber 38377-59-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,3,7 and 7 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 38377-59:
(7*3)+(6*8)+(5*3)+(4*7)+(3*7)+(2*5)+(1*9)=152
152 % 10 = 2
So 38377-59-2 is a valid CAS Registry Number.

Copper-catalysed: N -arylation of 5-aminopyrazoles: A simple route to pyrazolo[3,4- b] indoles

Chatterjee, Arpita,Murmu, Chudamani,Peruncheralathan, S.

supporting information, p. 6571 - 6581 (2020/11/07)

A copper-catalysed intramolecular N-arylation of 5-aminopyrazoles is demonstrated for the first time. Highly substituted pyrazolo[3,4-b]indoles are synthesized. In particular, the indole core is decorated with halogens and alkyl and methoxy groups. Furthermore, a selective N-arylation of unsymmetrical diaryl bromide containing pyrazoles is exemplified, resulting in valuable pyrazolo[1,5-a]benzimidazoles. This journal is
