74938-14-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74938-14-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,3 and 8 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 74938-14:
(7*7)+(6*4)+(5*9)+(4*3)+(3*8)+(2*1)+(1*4)=160
160 % 10 = 0
So 74938-14-0 is a valid CAS Registry Number.

2H-PYRROLE-1-OXIDES BY SELENIUM DIOXIDE DEHYDROGENATION OF PYRROLINE-1-OXIDES
Bender, H.,Doepp, D.
, p. 1833 - 1836 (2007/10/02)
Five different 2H-pyrrole-1-oxides have been prepared by dehydrogenation of their corresponding pyrroline-1-oxide precursors and characterized by 1,3-dipolar cycloadditions with dimethyl ethyne dicarboxylate and/or N-phenyl maleic imide.
