Check Digit Verification of cas no

The CAS Registry Mumber 1437872-98-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,7,8,7 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1437872-98:
(9*1)+(8*4)+(7*3)+(6*7)+(5*8)+(4*7)+(3*2)+(2*9)+(1*8)=204
204 % 10 = 4
So 1437872-98-4 is a valid CAS Registry Number.

Organoselenium and DMAP co-catalysis: Regioselective synthesis of medium-sized halolactones and bromooxepanes from unactivated alkenes

Verma, Ajay,Jana, Sadhan,Prasad, Ch. Durga,Yadav, Abhimanyu,Kumar, Sangit

, p. 4179 - 4182 (2016/03/19)

A catalytic system consisting of bis(4-methoxyphenyl)selenide and 4-(dimethylamino)pyridine (DMAP) has been developed for the regioselective synthesis of medium-sized bromo/iodo lactones and bromooxepanes possessing high transannular strain. 77Se NMR, mass spectrometry and theoretical studies reveal that the reaction proceeds via a quaternary selenium intermediate.

Patterned recognition of amines and ammonium ions by a stimuli-responsive foldamer-based hexameric oligophenol host

Sun, Chang,Ren, Changliang,Wei, Yuchen,Qin, Bo,Zeng, Huaqiang

supporting information, p. 5307 - 5309 (2013/06/27)

A stimuli-responsive hexameric oligophenol host undergoes amine-induced co-operative folding from a more fluorescent, more linear structure into less fluorescent, more curved or helically folded states, enabling easy identification and classification of the bound amine guests.
