54773-25-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 54773-25-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,7,7 and 3 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 54773-25:
(7*5)+(6*4)+(5*7)+(4*7)+(3*3)+(2*2)+(1*5)=140
140 % 10 = 0
So 54773-25-0 is a valid CAS Registry Number.

Utilization of Vinylsilanes in Cycloaddition Reactions
Padwa, Albert,MacDonald, J. Gavin
, p. 3189 - 3195 (2007/10/02)
The reaction of several vinylsilanes with benzonitrile oxide, 2-diazopropane, C-carboethoxy-N-phenylnitrile imine, and substituted 1,3-butadienes has been examined.The 1,3-dipolar cycloadditions followed frontier orbital predictions and gave silylated iso
