57015-12-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57015-12-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,0,1 and 5 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 57015-12:
(7*5)+(6*7)+(5*0)+(4*1)+(3*5)+(2*1)+(1*2)=100
100 % 10 = 0
So 57015-12-0 is a valid CAS Registry Number.

A STUDY ON KINETIC C-H-ACIDITY: THE α-EPIMERIZATION OF β-LACTONES
Mulzer, Johann,Zippel, Matthias
, p. 2165 - 2168 (2007/10/02)
The rate constants of the α-epimerization of the β-lactone 1 show a LFE-correlation with the solvent donicity parameters DN or B; additionally, the kinetic CH-acidity of 1 is unusually high.
