Check Digit Verification of cas no

The CAS Registry Mumber 23767-54-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,7,6 and 7 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 23767-54:
(7*2)+(6*3)+(5*7)+(4*6)+(3*7)+(2*5)+(1*4)=126
126 % 10 = 6
So 23767-54-6 is a valid CAS Registry Number.

A new entry of amination reagents for heteroaromatic C-H bonds: Copper-catalyzed direct amination of azoles with chloroamines at room temperature

Kawano, Tsuyoshi,Hirano, Koji,Satoh, Tetsuya,Miura, Masahiro

supporting information; experimental part, p. 6900 - 6901 (2010/07/05)

Chloroamine serves as an efficient amination reagent to the heteroaromatic C-H bond of azole under copper catalysis even at room temperature. This catalysis enables a rapid and concise construction of aminoazoles of great interest in biological and medicinal chemistry.
