146445-12-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 146445-12-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,4,4 and 5 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 146445-12:
(8*1)+(7*4)+(6*6)+(5*4)+(4*4)+(3*5)+(2*1)+(1*2)=127
127 % 10 = 7
So 146445-12-7 is a valid CAS Registry Number.

Mechanism of Wittig reaction with cyclic anhydrides
Kayser, Margaret M.,Hatt, Krista L.,Hooper, Donald L.
, p. 1985 - 1996 (2007/10/02)
The reactions of stabilized phosphoranes with cyclic anhydrides give enol-lactones as final products.The inital condensation, however, leads to the formation of acyclic adducts that are observable by NMR, can be easily trapped, and, in some cases, can be
