Check Digit Verification of cas no

The CAS Registry Mumber 139697-99-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,6,9 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 139697-99:
(8*1)+(7*3)+(6*9)+(5*6)+(4*9)+(3*7)+(2*9)+(1*9)=197
197 % 10 = 7
So 139697-99-7 is a valid CAS Registry Number.

A new route to 2-aryl-4-quinolones via palladium-catalyzed carbonylative coupling of o-iodoanilines with terminal arylacetylenes

Kalinin,Shostakovsky,Ponomaryov

, p. 373 - 376 (1992)

O-Iodoanilines undergo Pd-catalyzed intramolecular heterocyclization with terminal arylacetylenes in the presence of carbon monoxide to give 2-aryl-4-quinolones.

Syntheses of chromones and quinolones via Pd-catalyzed carbonylation of o-iodophenols and anilines in the presence of acetylenes

Torii, Sigeru,Okumoto, Hiroshi,Xu, Long He,Sadakane, Masahiro,Shostakovsky, Michel V.,Ponomaryov, Andrew B.,Kalinin, Valery N.

, p. 6773 - 6784 (2007/10/02)

Synthesis of 2-substituted chromones and quinolones has been performed by a Pd-catalyzed carbonylation of o-iodophenols or o-iodoanilines in the presence of terminal acetylenes in a high yield through coupling of halides and acetylenes followed by cyclization as a one-pot reaction.
