Check Digit Verification of cas no

The CAS Registry Mumber 1433956-41-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,3,9,5 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1433956-41:
(9*1)+(8*4)+(7*3)+(6*3)+(5*9)+(4*5)+(3*6)+(2*4)+(1*1)=172
172 % 10 = 2
So 1433956-41-2 is a valid CAS Registry Number.

Enantioselective bromoaminocyclization of allyl N-tosylcarbamates catalyzed by a chiral phosphine-Sc(OTf)3 complex

Huang, Deshun,Liu, Xiaoqin,Li, Lijun,Cai, Yudong,Liu, Weigang,Shi, Yian

supporting information, p. 8101 - 8104 (2013/07/19)

An effective enantioselective bromoaminocyclization of allyl N-tosylcarbamates catalyzed by a chiral phosphine-Sc(OTf)3 complex is described. A wide variety of optically active oxazolidinone derivatives containing various functional groups can be obtained with high enantioselectivities.
