72838-29-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 72838-29-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,8,3 and 8 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 72838-29:
(7*7)+(6*2)+(5*8)+(4*3)+(3*8)+(2*2)+(1*9)=150
150 % 10 = 0
So 72838-29-0 is a valid CAS Registry Number.

Substitution of fluorine in C6F5X (X = COOMe, CF3, CN, NO2) and pentafluoropyridine by the triethylgermyl group
Bardin, V.V.,Pressman, L.S.,Furin, G.G
, p. 55 - 57 (2007/10/02)
The perfluorinated arenes C6F5X (X=COOMe, CF3, CN, NO2) and pentafluoropyridine react with P(NEt2)3 and ClGeEt3, giving 4-XC6F4GeEt3 (or 4-GeEt3C5F4N) and P(NEt2)3FCl.
