Check Digit Verification of cas no

The CAS Registry Mumber 1613157-39-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,3,1,5 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1613157-39:
(9*1)+(8*6)+(7*1)+(6*3)+(5*1)+(4*5)+(3*7)+(2*3)+(1*9)=143
143 % 10 = 3
So 1613157-39-3 is a valid CAS Registry Number.

Catalytic asymmetric aminolactonization of 1,2-disubstituted alkenoic acid esters: Efficient construction of aminolactones with an all-carbon quaternary stereo-centre

Hajra, Saumen,Akhtar, Sk Md Samim,Aziz, Sk Mohammad

supporting information, p. 6913 - 6916 (2014/06/23)

Chiral BOX-Cu(OTf)2 catalyzed enantioselective aminolactonization of the tert-butyl ester of alkenoic acids has been developed via in situ aziridination using PhINNs as the nitrene source. It provides exclusively trans-γ- and δ-amino lactones including an additional all-carbon quaternary stereo-centre with up to 98% ee in good to excellent yields. the Partner Organisations 2014.
