Check Digit Verification of cas no
The CAS Registry Mumber 81971-39-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,9,7 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 81971-39:
(7*8)+(6*1)+(5*9)+(4*7)+(3*1)+(2*3)+(1*9)=153
153 % 10 = 3
So 81971-39-3 is a valid CAS Registry Number.

Iridium-Catalysed C-H Borylation of 2-Pyridones; Bisfunctionalisation of CC4
Honraedt, Aurélien,Niwetmarin, Worawat,Gotti, Cecilia,Campello, Hugo Rego,Gallagher, Timothy
, p. 3420 - 3429 (2018/07/13)
The high regioselectivity associated with the iridium-catalysed borylation of pyridones has been exploited to provide a very direct and efficient entry to C(10) doubly substituted CC4 variants of cytisine. Two approaches have been evaluated based on (i) C-H activation of cytisine (or an N-substituted derivative) followed by N-alkylation (to enable dimer formation) and (ii) direct C-H activation and borylation of CC4 itself. Both approaches provide access to C(10)-functionalized CC4 derivatives, but direct borylation of CC4 allows for a wider range of functional group interconversions to be tolerated.
BROMINATION OF 1-ALKYL-2-PYRIDONES

The corresponding monobromides were obtained in the bromination of 1-alkyl-2-pyridones with bonded bromine (with N-bromosuccinimide and dioxane dibromide).The conditions under which the yields of the mixtures of isomers were 60-80percent, and almost no dibromides were obtained, were found.It was established that the ratios of the 3- and 5-bromo isomers depend on the character of the brominating agent.
