Check Digit Verification of cas no

The CAS Registry Mumber 62838-18-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,8,3 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 62838-18:
(7*6)+(6*2)+(5*8)+(4*3)+(3*8)+(2*1)+(1*8)=140
140 % 10 = 0
So 62838-18-0 is a valid CAS Registry Number.

Synthesis of 3,3'-(1,2-ethanediyl)bis and their heteroaromatic analogues

Zachariah, Lata,Reddy, Satyanarayana

, p. 826 - 829 (2007/10/02)

Condensation of N,N'-ethanediylbisbenzamide (I) with aldehydes in 1:2 molar proportions in hot acetic acid results in 3,3'-(1,2-ethanediyl)bis (II).Dehydrogenation of II using nitrobenzene, potassium permanganate in acetone or palladium-charcoal leads to 3,3'-(1,2-ethanediyl)bis (V).All the compounds have been characterised by elemental analyses and mass, IR and 1H NMR spectral data.
