Check Digit Verification of cas no

The CAS Registry Mumber 81261-71-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,2,6 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 81261-71:
(7*8)+(6*1)+(5*2)+(4*6)+(3*1)+(2*7)+(1*1)=114
114 % 10 = 4
So 81261-71-4 is a valid CAS Registry Number.

Microwave-assisted simple synthesis of 2-anilinopyrimidines by the reaction of 2-chloro-4,6-dimethylpyrimidine with aniline derivatives

Angelini, Guido,Campestre, Cristina,Gasbarri, Carla,Kóti, János,Keglevich, Gy?rgy,Scotti, Luca

, p. 12249 - 12254 (2020)

A series of 2-anilinopyrimidines including novel derivatives has been obtained from 2-chloro-4,6-dimethylpyrimidine by aromatic nucleophilic substitution with differently substituted anilines under microwave conditions. The substituents had a significant impact on the course and efficiency of the reaction. The results reported herein demonstrate the efficacy of microwaves in the synthesis of the title heterocyclic compounds as compared to the results obtained with conventional heating. The 2-anilinopyrimidines described are of potential bioactivity.
