78627-32-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78627-32-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,6,2 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 78627-32:
(7*7)+(6*8)+(5*6)+(4*2)+(3*7)+(2*3)+(1*2)=164
164 % 10 = 4
So 78627-32-4 is a valid CAS Registry Number.

Synthesis of Symmetrical Diaminocarbodiphosphoranes R2NPh2P=C=PPh2NR2
Appel, Rolf,Waid, Karl
, p. 131 - 134 (2007/10/02)
The hitherto unknown symmetrical diamino carbodiphosphoranes R2NPh2P=C=PPh2NR2 (5a-d, R = CH3, Et, nPr, nBu) are obtained in good yield by NaH dehydrohalogenation of the corresponding aminophosphonium salts (3a-d). 3a-d can be prepared by aminol
