110950-15-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 110950-15-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,0,9,5 and 0 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 110950-15:
(8*1)+(7*1)+(6*0)+(5*9)+(4*5)+(3*0)+(2*1)+(1*5)=87
87 % 10 = 7
So 110950-15-7 is a valid CAS Registry Number.

THE STEREOSELECTIVITY OF KETAL CLAISEN REARRANGEMENTS WITH KETALS OF SIMPLE CYCLIC KETONES
Daub, G. William,Griffith, David A.
, p. 6311 - 6314 (1986)
Claisen rearrangements of the ketals of cyclopentanone, cyclohexanone and cycloheptanone give mixtures of syn and anti products favoring the syn isomer by as much as 19:1.The selectivity is attenuated by enolization processes in the 5- and 6-membered ring systems.
