1427-33-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1427-33-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,2 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1427-33:
(6*1)+(5*4)+(4*2)+(3*7)+(2*3)+(1*3)=64
64 % 10 = 4
So 1427-33-4 is a valid CAS Registry Number.

Preparation of 1,1,2-trifluoro-2-trimethylsilylethylene
Jairaj, Vinod,Burton, Donald J.
, p. 75 - 77 (2003)
1,1,2-Trifluoro-2-trimethylsilylethylene can be readily prepared via the Cu(I)Br catalyzed silylation of the 1,1,2-trifluoroethenylzinc reagent with Me3SiCl. The reaction is easily scaled-up, isolation of the trifluorovinylsilane is facile, and
