Check Digit Verification of cas no

The CAS Registry Mumber 65490-70-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,4,9 and 0 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 65490-70:
(7*6)+(6*5)+(5*4)+(4*9)+(3*0)+(2*7)+(1*0)=142
142 % 10 = 2
So 65490-70-2 is a valid CAS Registry Number.

N-Pyridinyl Sulfilimines as a Source for α-Imino Gold Carbenes: Access to 2-Amino-Substituted N-Fused Imidazoles

supporting information, p. 1598 - 1601 (2019/03/11)

Gold-catalyzed formal 1,3-dipolar annulation between readily accessible N-pyridinylsulfilimines and ynamides is reported. A diverse set of imidazole derivatives is prepared from the corresponding sulfilimines and ynamides. These functionalized cyclic products can undergo further transformations to afford diverse imidazole frameworks. Moreover, in situ synthesis is feasible and shows good potential in the synthesis of nucleoside analogues.
