284040-83-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 284040-83-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,4,0,4 and 0 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 284040-83:
(8*2)+(7*8)+(6*4)+(5*0)+(4*4)+(3*0)+(2*8)+(1*3)=131
131 % 10 = 1
So 284040-83-1 is a valid CAS Registry Number.

Synthesis and reactivity of 4-silylated oxazoles
Ducept, Pascal C.,Marsden, Stephen P.
, p. 692 - 294 (2007/10/03)
Treatment of (triethylsilyl)diazoacetates with rhodium(II) octanoate and a range of substituted nitriles generates trisubstituted oxazoles bearing a triethylsilyl group in the 4-position. Fluoride-mediated desilylation yields 3,5-disubstituted oxazoles, w
