Check Digit Verification of cas no

The CAS Registry Mumber 1547490-89-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,4,7,4,9 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1547490-89:
(9*1)+(8*5)+(7*4)+(6*7)+(5*4)+(4*9)+(3*0)+(2*8)+(1*9)=200
200 % 10 = 0
So 1547490-89-0 is a valid CAS Registry Number.

Stereoselective synthesis of C-sulfonylated aziridines from halomethyl phenyl sulfone and N-tert-butanesulfinyl imines

Li, Ya,Huang, Haiji,Wang, Zhen,Yang, Fan,Li, Desheng,Qin, Bo,Ren, Xinfeng

, p. 969 - 973 (2014/01/06)

A highly efficient and stereoselective synthesis of C-sulfonylated aziridines is developed by using a one-step aza-Darzens reaction. When sodium bis(trimethylsilyl)amide (NaHMDS) was used as the base, bromomethyl phenyl sulfone reacted with N-tert-butanesulfinyl imines to afford the 2-sulfonylated aziridine products in very good yields and with stereoselectivities up to 50:1.
