Check Digit Verification of cas no
The CAS Registry Mumber 143029-08-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,0,2 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 143029-08:
(8*1)+(7*4)+(6*3)+(5*0)+(4*2)+(3*9)+(2*0)+(1*8)=97
97 % 10 = 7
So 143029-08-7 is a valid CAS Registry Number.

Novel synthesis of 1,4-diazacrown ethers by reductive coupling of aromatic diimines
Shono,Kise,Okazaki
, p. 3347 - 3350 (2007/10/02)
The electroreduction or chemical reduction with zinc powder has been found to be effective to intramolecular coupling of aromatic diimines yielding 1,4-diazacrown ethers. The latter reduction was particularly effective to formation of 1,4-diaza-12-crown-4
