669053-34-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 669053-34-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,9,0,5 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 669053-34:
(8*6)+(7*6)+(6*9)+(5*0)+(4*5)+(3*3)+(2*3)+(1*4)=183
183 % 10 = 3
So 669053-34-3 is a valid CAS Registry Number.

Formamidine Ureas as Tunable Electrophiles
Diaz, David D.,Finn
, p. 303 - 309 (2007/10/03)
Formamidine urea compounds exchange imine fragments with primary nitrogen nucleophiles, allowing the preparation of a variety of derivatives from a single precursor. The reactivities of these species are governed primarily by the electron-donating power o
