652154-31-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 652154-31-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,2,1,5 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 652154-31:
(8*6)+(7*5)+(6*2)+(5*1)+(4*5)+(3*4)+(2*3)+(1*1)=139
139 % 10 = 9
So 652154-31-9 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
