99784-40-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99784-40-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,7,8 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 99784-40:
(7*9)+(6*9)+(5*7)+(4*8)+(3*4)+(2*4)+(1*0)=204
204 % 10 = 4
So 99784-40-4 is a valid CAS Registry Number.

On the mechanism of lithium amide-induced rearrangements of Q-substituted cyclopentene oxides to cyclopentenols
Hodgson, David M.,Gibbs, Andrew R.
, p. 8907 - 8910 (2007/10/03)
The preparation and lithium amide-induced rearrangements of epoxides 4, 10 (R = Bn, TBS) are described, providing insight into the rearrangement mechanisms which operate in such systems.
