Check Digit Verification of cas no
The CAS Registry Mumber 1940-27-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,4 and 0 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1940-27:
(6*1)+(5*9)+(4*4)+(3*0)+(2*2)+(1*7)=78
78 % 10 = 8
So 1940-27-8 is a valid CAS Registry Number.

Synthesis of symmetrical dinitro-and diamino-substituted Troeger's base analogues
Sturala, Jiri,Cibulka, Radek
, p. 7066 - 7074 (2013/02/21)
This report describes a new synthetic approach to symmetrical diamino-substituted Troeger's base analogues, allowing the synthesis of 1,7-, and 4,10-diamino derivatives with no additional substituents and of 3,9-diamino derivative with methyl groups in the 1-, 4-, 7-and 10-positions. The synthesis uses regioselective nitration of dihalo-substituted-or tetrahalo-substituted Troeger's bases followed either by hydrogenation of the nitro functions accompanied by removal of halogen atoms or alternatively by chemoselective reduction of nitro groups to obtain the dihalo-diamino- substituted Troeger's base analogues. The 2,8-diamino derivatives, not accessible by this approach, can be prepared by Buchwald-Hartwig amination of the 2,8-dibromo-substituted Troeger's bases.
