Check Digit Verification of cas no

The CAS Registry Mumber 156697-63-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,6,9 and 7 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 156697-63:
(8*1)+(7*5)+(6*6)+(5*6)+(4*9)+(3*7)+(2*6)+(1*3)=181
181 % 10 = 1
So 156697-63-1 is a valid CAS Registry Number.

A new synthesis of 2-methyleneaziridines

De Kimpe, Norbert,De Smaele, Dirk,Sakonyi, Zsolt

, p. 2448 - 2452 (2007/10/03)

A new synthetic route leading to 2-methyleneaziridines has been developed by base-induced 1,2-dehydrobromination of 2-(bromomethyl)aziridines. Several base-solvent pairs did not lead to 2-methyleneaziridines. Only potassium tert-butoxide in tetrahydrofuran afforded 2-methyleneaziridines in competition with the substitution products, i.e. 2-(tert-butoxymethyl)aziridines. Various attempted functionalizations of 1-(arylmethyl)-2-methyleneaziridines failed, but they proved to be excellent substrates for the synthesis of β-lactam derivatives, i.e. 1-(arylmethyl)-2-iminoazetidines, through ring expansion with azides carrying electron-withdrawing substituents.
