Check Digit Verification of cas no

The CAS Registry Mumber 194350-35-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,4,3,5 and 0 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 194350-35:
(8*1)+(7*9)+(6*4)+(5*3)+(4*5)+(3*0)+(2*3)+(1*5)=141
141 % 10 = 1
So 194350-35-1 is a valid CAS Registry Number.

Synthesis and reactivity of alkyl (4-aminothien-3-yl)carbamates

Brugier, Delphine,Outurquin, Francis,Paulmier, Claude

, p. 10331 - 10344 (2007/10/03)

Monocarbamates 2 have been prepared from 3,4-diaminothiophene 1 and were alkylated on the thiophene nucleus using an aldehyde and selenophenol, under acid catalysis. This reaction has allowed the access to 2-alkyl 3,4-diaminothiophenes 9, 3,5-diaminodithieno[3,2-b:2',3'-e]pyridines 10 and 1-alkyl thieno[3,4-d]imidazolones 13.
