Check Digit Verification of cas no

The CAS Registry Mumber 1334146-19-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,4,1,4 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1334146-19:
(9*1)+(8*3)+(7*3)+(6*4)+(5*1)+(4*4)+(3*6)+(2*1)+(1*9)=128
128 % 10 = 8
So 1334146-19-8 is a valid CAS Registry Number.

Direct α-Imination of N-Acyl Pyrazoles with Nitrosoarenes

Volpe, Chiara,Meninno, Sara,Mirra, Giulia,Overgaard, Jacob,Capobianco, Amedeo,Lattanzi, Alessandra

supporting information, p. 5305 - 5309 (2019/07/03)

Unprecedented α-imino N-acyl pyrazoles were efficiently and selectively prepared through the 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD)-catalyzed reaction of nitrosoarenes with N-acyl pyrazoles via an N-nitroso aldol reaction/dehydration sequence. The α-imino acyl pyrazoles were demonstrated to be new versatile intermediates for practical one-pot syntheses of α-imino amides, dipeptide precursors, esters, and β-amino alcohols. The synthetic method competes with known protocols in terms of ready availability of the reagents and catalyst, mild and catalytic reaction conditions, gram-scale applicability, and scope of the α-imino acid derivatives achievable.
