99440-36-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 99440-36-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,4,4 and 0 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 99440-36:
(7*9)+(6*9)+(5*4)+(4*4)+(3*0)+(2*3)+(1*6)=165
165 % 10 = 5
So 99440-36-5 is a valid CAS Registry Number.

β-hydroxy Esters: (E)- versus (Z)-Enolate Geometry in Dianionic Claisen Rearrangements
Kurth, Mark J.,Beard, Richard L.
, p. 4085 - 4088 (2007/10/02)
Control elements operative in the β-hydroxy ester dianionic Claisen rearrangements are probed.Stereochemistry at Cβ dictates face selectivity at Cα and Cβ' in 1->2-5, but only to the extent that it controls ester enolate g
