Check Digit Verification of cas no

The CAS Registry Mumber 1245623-78-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,5,6,2 and 3 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1245623-78:
(9*1)+(8*2)+(7*4)+(6*5)+(5*6)+(4*2)+(3*3)+(2*7)+(1*8)=152
152 % 10 = 2
So 1245623-78-2 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

, p. 5305 - 5309 (2019)

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.
