74407-97-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74407-97-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,0 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 74407-97:
(7*7)+(6*4)+(5*4)+(4*0)+(3*7)+(2*9)+(1*7)=139
139 % 10 = 9
So 74407-97-9 is a valid CAS Registry Number.

STEREOSPECIFIC FORMATION OF AMIDINES BY 1,1-ADDITION OF AMINES TO ISOCYANIDES
Hegarty, Anthony F.,Chandler, Anne
, p. 885 - 888 (2007/10/02)
Addition of secondary amines to isonitriles in the presence of AgCl at low temperature gives isolable but thermodynamically unstable Z-amidines; only the more stable 6E undergoes ring expansion to the imidazoline 7.
