Check Digit Verification of cas no

The CAS Registry Mumber 80830-66-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,8,3 and 0 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 80830-66:
(7*8)+(6*0)+(5*8)+(4*3)+(3*0)+(2*6)+(1*6)=126
126 % 10 = 6
So 80830-66-6 is a valid CAS Registry Number.

C2-Selective, Functional-Group-Divergent Amination of Pyrimidines by Enthalpy-Controlled Nucleophilic Functionalization

Ham, Won Seok,Choi, Hoonchul,Zhang, Jianbo,Kim, Dongwook,Chang, Sukbok

, p. 2885 - 2892 (2022/02/23)

Synthesis of heteroaryl amines has been an important topic in organic chemistry because of their importance in small-molecule discovery. In particular, 2-Aminopyrimidines represent a highly privileged structural motif that is prevalent in bioactive molecules, but a general strategy to introduce the pyrimidine C2-N bonds via direct functionalization is elusive. Here we describe a synthetic platform for site-selective C-H functionalization that affords pyrimidinyl iminium salt intermediates, which then can be transformed into various amine products in situ. Mechanism-based reagent design allowed for the C2-selective amination of pyrimidines, opening the new scope of site-selective heteroaryl C-H functionalization. Our method is compatible with a broad range of pyrimidines with sensitive functional groups and can access complex aminopyrimidines with high selectivity.
