206876-90-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 206876-90-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,6,8,7 and 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 206876-90:
(8*2)+(7*0)+(6*6)+(5*8)+(4*7)+(3*6)+(2*9)+(1*0)=156
156 % 10 = 6
So 206876-90-6 is a valid CAS Registry Number.

Expanded Chemistry of Formamidine Ureas
Diaz, David D.,Finn
, p. 43 - 46 (2007/10/03)
(Equation presented) Formamidine ureas display a rich manifold of reactivity. Thiols induce substitution at the carbonyl carbon to give thiolcarbamates; base-mediated alkylation and acylation occurs at the terminal urea nitrogen, and a new fragmentation/acylation pathway has been uncovered with isocyanates.
