Check Digit Verification of cas no

The CAS Registry Mumber 1639463-83-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,9,4,6 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1639463-83:
(9*1)+(8*6)+(7*3)+(6*9)+(5*4)+(4*6)+(3*3)+(2*8)+(1*3)=204
204 % 10 = 4
So 1639463-83-4 is a valid CAS Registry Number.

One pot photoredox decarboxylation reaction of N-cyano(α-bromo- α-phenyl)methylanilines leading to synthesis of four-membered cyclic carbamates

Kaur, Manpreet,Singh, Baldev

, p. 850 - 853 (2014/06/10)

A new four-membered cyclic carbamates have been synthesized through solar irradiation of N-cyano(α-bromo-α-phenyl)methylanilines in their aqueous methanolic solution using iodide salt in basic medium. These compounds have been characterized as 3,4-diphenyl-1,3oxazetidin-2-one through their elemental analysis, IR, 1H-NMR, 13C-NMR, and mass spectral studies.
