72938-18-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72938-18-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,9,3 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 72938-18:
(7*7)+(6*2)+(5*9)+(4*3)+(3*8)+(2*1)+(1*8)=152
152 % 10 = 2
So 72938-18-2 is a valid CAS Registry Number.

Electrophilic Bromination of Fluoro Olefins: Syn vs. Anti Addition
Naae, Douglas G.
, p. 1394 - 1401 (2007/10/02)
The ionic addition of bromine in glacial acetic acid to 4-RC6H4CF=CFX (R = CO2H, Br, H, CH3, OCH3; X = Cl, CF3) and 4-RC6H4CH=CFCl (R = Br, CH3) has been studied.For all olefins the 1,2-dibromo adduct is the predominant product, with a minor amount of the
