40474-27-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 40474-27-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,4,7 and 4 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 40474-27:
(7*4)+(6*0)+(5*4)+(4*7)+(3*4)+(2*2)+(1*7)=99
99 % 10 = 9
So 40474-27-9 is a valid CAS Registry Number.

Phosphinimine-borane combinations in frustrated Lewis pair chemistry
Jiang, Chunfang,Stephan, Douglas W.
, p. 630 - 637 (2013)
The phosphinimines Ph3PNR (R = Ph 1, C6F 52, tBu 3) are combined with B(C6F5) 3 in an effort to explore the frustrated Lewis pair (FLP) chemistry. While compound 1 is shown to form an adduc
