Check Digit Verification of cas no
The CAS Registry Mumber 150338-25-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,0,3,3 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 150338-25:
(8*1)+(7*5)+(6*0)+(5*3)+(4*3)+(3*8)+(2*2)+(1*5)=103
103 % 10 = 3
So 150338-25-3 is a valid CAS Registry Number.

Enantioselective epoxidation of 2-substituted 1,4-naphthoquinones using gem-dihydroperoxides
Bunge, Alexander,Hamann, Hans-Jürgen,McCalmont, Eve,Liebscher, Jürgen
, p. 4629 - 4632 (2009)
New gem-dihydroperoxides were successfully used for DBU-promoted enantioselective epoxidation of 2-substituted 1,4-naphthoquinones. The corresponding 1,4-naphthoquinone epoxides were obtained in yields up to 97% and ee's up to 82%.
