Check Digit Verification of cas no
The CAS Registry Mumber 5182-90-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,8 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5182-90:
(6*5)+(5*1)+(4*8)+(3*2)+(2*9)+(1*0)=91
91 % 10 = 1
So 5182-90-1 is a valid CAS Registry Number.

Azole-N-acetonitriles as carbonyl synthons: A one-pot preparation of heteroaryl amides from halides

, p. 2323 - 2326 (2007/10/03)
Azole-N-acetonitrile derivatives were utilized as synthons for an ambident carbonyl moiety via a strategy relying upon sequential base-mediated S NAr substitution of a 2-halo heterocycle, in situ oxidation, and amine displacement. This strategy allows prompt and efficient synthesis of N-containing heteroaryl amides directly from the corresponding halides via a one-pot process.
