Check Digit Verification of cas no

The CAS Registry Mumber 1438286-68-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,8,2,8 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1438286-68:
(9*1)+(8*4)+(7*3)+(6*8)+(5*2)+(4*8)+(3*6)+(2*6)+(1*8)=190
190 % 10 = 0
So 1438286-68-0 is a valid CAS Registry Number.

An efficient coupling of N-tosylhydrazones with 2-halopyridines: Synthesis of 2-α-styrylpyridines endowed with antitumor activity

, p. 3664 - 3673 (2013/06/26)

The synthesis of 2-α-styrylpyridines has been carried out by using the coupling of polyoxygenated N-tosylhydrazones with various 2-halopyridines. We demonstrated that the use of a catalytic amount of PdCl2(MeCN) 2 in combination with a bidentate ferrocene DPPF or a monodentate alkyl phosphine tBu2MeP-HBF4 constitutes an efficient protocol for this coupling, providing 2-α-styrylpyridines 2 in satisfactory to good yields. Among several polyoxygenated derivatives 2 evaluated, compound 2aa was found to exhibit excellent antiproliferative and antimitotic activities comparable to that of the reference compound isoCA-4.
