40925-11-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 40925-11-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,9,2 and 5 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 40925-11:
(7*4)+(6*0)+(5*9)+(4*2)+(3*5)+(2*1)+(1*1)=99
99 % 10 = 9
So 40925-11-9 is a valid CAS Registry Number.

MECHANISM OF NUCLEOPHILIC SUBSTITUTION AT TRICOVALENT PHOSPHORUS
Dahl, Otto
, p. 201 - 204 (2007/10/02)
The mechanism of substitution reactions at tricovalent phosphorus, mainly the system + ROH, is discussed on the basis of stereochemistry, catalysis, kinetics and substituent effects.
