143262-68-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143262-68-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,2,6 and 2 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 143262-68:
(8*1)+(7*4)+(6*3)+(5*2)+(4*6)+(3*2)+(2*6)+(1*8)=114
114 % 10 = 4
So 143262-68-4 is a valid CAS Registry Number.

1,3-Dipolar cycloaddition reactions of a heterocyclic nitrone
Ali,Almuallem
, p. 5273 - 5282 (2007/10/02)
A study of the regio- and stereo-chemical behaviour of the 1,3-dipolar cycloaddition of a series of alkenes with 5,6-dihydro-1,4-oxazine-4-oxide (1) has been carried out. Stereoselectivity in these cycloadditions has been explained in terms of steric fact
