Check Digit Verification of cas no

The CAS Registry Mumber 90838-85-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,8,3 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 90838-85:
(7*9)+(6*0)+(5*8)+(4*3)+(3*8)+(2*8)+(1*5)=160
160 % 10 = 0
So 90838-85-0 is a valid CAS Registry Number.

Substituted Dihydropyridine Synthesis by Dearomatization of Pyridines

Fliege, Julian,Glorius, Frank,Heusler, Arne,Wagener, Tobias

supporting information, p. 13793 - 13797 (2021/05/13)

Dearomatization is an effective method to transform readily available N-heterocycles into partially saturated motifs. Manipulation of dihydro-derivatives holds great potential and provides access to a variety of semi-saturated N-heterocyclic building blocks. However, current strategies are limited in scope and the use of sensitive reagents restricts the applicability in synthetic laboratories. Herein, we report the synthesis of a broad variety of N-substituted 1,4- and 1,2-dihydropyridines by very mild and selective reduction with amine borane for the first time.
