Check Digit Verification of cas no
The CAS Registry Mumber 381228-00-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,8,1,2,2 and 8 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 381228-00:
(8*3)+(7*8)+(6*1)+(5*2)+(4*2)+(3*8)+(2*0)+(1*0)=128
128 % 10 = 8
So 381228-00-8 is a valid CAS Registry Number.

Synthesis and structure of O-silylated 2-polyfluoroacyl-cycloalkanones
Sevenard,Roeschenthaler
, p. 911 - 918 (2001)
2-Acyl-cycloalkanones containing polyfluoroalkyl groups react with dichlorodimethylsilane to form the corresponding heterocyclic bis-enol derivatives. The reaction of 2-polyfluoroacyl-cycloalkanones with chlorotrimethylsilane leads to mixtures of the corr
