Check Digit Verification of cas no

The CAS Registry Mumber 1345042-78-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,5,0,4 and 2 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1345042-78:
(9*1)+(8*3)+(7*4)+(6*5)+(5*0)+(4*4)+(3*2)+(2*7)+(1*8)=135
135 % 10 = 5
So 1345042-78-5 is a valid CAS Registry Number.

Intramolecular cycloadditions of photogenerated azaxylylenes with oxadiazoles provide direct access to versatile polyheterocyclic ketopiperazines containing a spiro-oxirane moiety

Kumar, N. N. Bhuvan,Kuznetsov, Dmitry M.,Kutateladze, Andrei G.

, p. 438 - 441 (2015/03/03)

Photogenerated azaxylylenes undergo intramolecular cycloadditions to 1,3,4-oxadiazole pendants, which are accompanied by concomitant release of dinitrogen, yielding functionalized ketopiperazinoquinolinols containing an oxirane moiety fused to the quinolinole moiety while spiro-connected to diketopiperazine. These primary photoproducts are reactive versatile intermediates which can be further derivatized under nucleophilic SN1- or SN2-like ring opening of the oxirane moiety. The oxidized quinolinones undergo new rearrangements under the conditions of the Schmidt reaction, leading to unprecedented triazacanoindolinones.
