Check Digit Verification of cas no

The CAS Registry Mumber 56172-15-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,1,7 and 2 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 56172-15:
(7*5)+(6*6)+(5*1)+(4*7)+(3*2)+(2*1)+(1*5)=117
117 % 10 = 7
So 56172-15-7 is a valid CAS Registry Number.

Regio- and enantioselective Baeyer-Villiger oxidation: Kinetic resolution of racemic 2-substituted cyclopentanones

supporting information, p. 3938 - 3941 (2014/08/18)

A kinetic resolution of racemic 2-substituted cyclopentanones via highly regio- and enantioselective Baeyer-Villiger oxidation has been successfully developed. The reaction could afford the normal 6-substituted δ-lactones in up to 98% ee and >19/1 regioselectivity. Meanwhile, the unreacted ketones were recovered in excellent ee values (up to 98%). It represents the best results of the kinetic resolution of racemic 2-substituted cyclopentanones via nonenzymic asymmetric BV oxidation.
