Check Digit Verification of cas no

The CAS Registry Mumber 128721-22-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,7,2 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 128721-22:
(8*1)+(7*2)+(6*8)+(5*7)+(4*2)+(3*1)+(2*2)+(1*2)=122
122 % 10 = 2
So 128721-22-2 is a valid CAS Registry Number.

SYNTHESIS AND REACTIVITY OF 2-(1,3-DITHIAN-2-YL)INDOLES. III. INFLUENCE OF THE INDOLE PROTECTIVE N-PHENYLSULFONYL GROUP

Rubiralta, Mario,Diez, Anna,Reig, Ignasi,Castells, Josep,Bettiol, Jean-Luc,et al.

, p. 173 - 186 (2007/10/02)

Formation of the anion of 2-(1,3-dithian-2-yl)indoles was shown to be possible when the indole nitrogen is protected by a p-methoxyphenylsulfonyl group.In contrast to the corresponding N-phenylsulfonylindole dithiane 1, the anion of dithiane 2 reacts efficiently with electrophiles.The influence of the indole protective group on the metallation of 2-bis(ethylthio)-methyl-1-(phenylsulfonyl)indole (14) and the corresponding sulfoxide 24 with n-butyllithium is also reported.
