Check Digit Verification of cas no

The CAS Registry Mumber 58007-81-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,0,0 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 58007-81:
(7*5)+(6*8)+(5*0)+(4*0)+(3*7)+(2*8)+(1*1)=121
121 % 10 = 1
So 58007-81-1 is a valid CAS Registry Number.

Mesoions as Versatile Intermediates in Tetrathiafulvalene Synthesis

Jorgensen, M.,Lerstrup, K. A.,Bechgaard, K.

, p. 5684 - 5688 (2007/10/02)

Fourteen new alkylthio-substituted tetrathiafulvalene (TTF) donors have been prepared via the mesoionic 2-(N,N-dialkylamino)-5-methyl-1,3-dithiolium-4-thiolates 4.By S-alkylation with alkyl halogenides and alkyl dihalogenides, 4 was transformed into a variety of mono- and bis-1,3-dithiolium salts 5.Coupling of 5 with the anion of 4,5-dimethyl-2H-1,3-dithiole-2-phosphonate ester 6 yielded a series of bis(tetrathiafulvalenes) 2 and (alkylthio)tetrathiafulvalenes 3.By conventional methods, 5 was coupled to bis(alkylthio)tetrathiafulvalenes.The synthesis of 4 was improved.An N,N-dialkyldithiocarbamate salt was allowed to react with a 2-halo carboxylic acid to yield a 1-(carboxyalkyl)-N,N-dialkyldithiocarbamate ester 10, which was then transformed into 4.The electrochemistry of the new TTFs is reported.
