231630-07-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 231630-07-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,1,6,3 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 231630-07:
(8*2)+(7*3)+(6*1)+(5*6)+(4*3)+(3*0)+(2*0)+(1*7)=92
92 % 10 = 2
So 231630-07-2 is a valid CAS Registry Number.

Efficient synthesis of N1- or N3- substituted thieno[2,3-d]imidazol- 2-ones
Fabis, Frederic,Jolivet-Fouchet, Sandrine,Rault, Sylvain
, p. 6167 - 6174 (2007/10/03)
N1- or N3-substituted thieno[2,3-d]imidazol-2-one derivatives are selectively obtained after N-alkylation of thiaisatoic anhydrides followed by formation of the N-substituted aminocarbonyl azides and Curtius rearrangement.
