116659-61-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 116659-61-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,6,5 and 9 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 116659-61:
(8*1)+(7*1)+(6*6)+(5*6)+(4*5)+(3*9)+(2*6)+(1*1)=141
141 % 10 = 1
So 116659-61-1 is a valid CAS Registry Number.

New 1,3-diazadienes used in heterocyclic synthesis
Friot, Celine,Reliquet, Alain,Reliquet, Francoise,Meslin, Jean Claude
, p. 695 - 702 (2007/10/03)
The synthesis of dihydropyrimidines, dihydropyrimidinones and thiadiazine-1,1-dioxides starting from neutral or cationic 2-methylthio-1,3- diazadienes is described. Addition of H2S followed by loss of methanethiol led to the corresponding thiocarbonyl compounds.
