Check Digit Verification of cas no

The CAS Registry Mumber 41939-97-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,9,3 and 9 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 41939-97:
(7*4)+(6*1)+(5*9)+(4*3)+(3*9)+(2*9)+(1*7)=143
143 % 10 = 3
So 41939-97-3 is a valid CAS Registry Number.

The discovery of pyridinium 1,2,4-triazines with enhanced performance in bioconjugation reactions

Siegl, Sebastian J.,Dzijak, Rastislav,Vázquez, Arcadio,Pohl, Radek,Vrabel, Milan

, p. 3593 - 3598 (2017/07/10)

1,2,4-Triazines have recently been identified as versatile dienes participating in the inverse electron-demand Diels-Alder reaction with strained dienophiles. However, their widespread utility in bioconjugation reactions is still limited. Herein, we repor

The synthesis of two new isonitrosoacetophenone derivatives and investigation of their ni(ii), Co(II), Cu(II), and Zr(IV) complexes
