64978-82-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 64978-82-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,9,7 and 8 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 64978-82:
(7*6)+(6*4)+(5*9)+(4*7)+(3*8)+(2*8)+(1*2)=181
181 % 10 = 1
So 64978-82-1 is a valid CAS Registry Number.

Condensations of Indeno-1,2-dithioles Yielding Diindenothiopyran Derivatives

Hartke, Klaus,Hoederath, Wolfgang,Krampitz, Dieter

, p. 968 - 976 (1985)

Indeno-1,2-dithioles 1 "dimerize" under acid catalysis by loss of two sulfur atoms to form diindenothiopyrans 2I/II.An analogous reaction is known for 3-methyl-5-phenyl-1,2-dithiolylium perchlorate (3) which condenses in glacial acetic acid/pyridine to the isomeric thiopyrans 4I/II.Reactions of 1-acyl-2-indanones 13 in acetic anhydride/perchloric acid yield the oxygen compounds 14 and 15, which are structurally analogous to 2I/2II.
