Check Digit Verification of cas no

The CAS Registry Mumber 1397644-41-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,7,6,4 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1397644-41:
(9*1)+(8*3)+(7*9)+(6*7)+(5*6)+(4*4)+(3*4)+(2*4)+(1*1)=205
205 % 10 = 5
So 1397644-41-5 is a valid CAS Registry Number.

Pentanidium-catalyzed enantioselective α-hydroxylation of oxindoles using molecular oxygen

Yang, Yuanyong,Moinodeen, Farhana,Chin, Willy,Ma, Ting,Jiang, Zhiyong,Tan, Choon-Hong

, p. 4762 - 4765 (2013/01/15)

Pentanidium-catalyzed α-hydroxylation of 3-substituted-2-oxindoles using molecular oxygen has been developed with good yields and enantioselectivities. This reaction does not require an additional reductant such as triethyl phosphite, which was typically added to reduce the peroxide intermediate. The reaction was demonstrated to consist of two-steps: an enantioselective formation of hydroperoxide oxindole and a kinetic resolution of the hydroperoxide oxindole via reduction with enolates generated from the oxindoles.
