143642-90-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 143642-90-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,6,4 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 143642-90:
(8*1)+(7*4)+(6*3)+(5*6)+(4*4)+(3*2)+(2*9)+(1*0)=124
124 % 10 = 4
So 143642-90-4 is a valid CAS Registry Number.

A novel rearrangement reaction accompanying alkyl metaphosphate extrusion on low-temperature photolysis of 2,3-oxaphosphabicyclo[2.2.2]octene derivatives

Quin,Wu,Lukes,Day

, p. 3975 - 3978 (1992)

On photolysis in propionitrile or THF solutions at -75°, three phosphonates (1-adamantyl, neopentyl, and ethyl as O-substituents) with the 2,3-oxaphosphabicyclo[2.2.2]octene ring system underwent extensive rearrangement accompanying the usual result at room temperature of metaphosphate extrusion. The rearrangemen product contains a cyclopropane ring, arising from detachment of the bridgehead-bound oxygen followed by attack on the double bond and subsequent ring closure. These rearrangement does not occur with related phosphonamides but has been detected with a phosphine oxide.
