Colorless liquid.

Check Digit Verification of cas no

The CAS Registry Mumber 157-40-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,5 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 157-40:
(5*1)+(4*5)+(3*7)+(2*4)+(1*0)=54
54 % 10 = 4
So 157-40-4 is a valid CAS Registry Number.

Azo-coupling and reduction of cyclopropanediazonium ions in the reactions with polyhydroxyarenes and aminophenols

Shulishov,Klimenko,Korolev,Kostyuchenko,Okonnishnikova,Tomilov

experimental part, p. 1703 - 1711 (2011/04/23)

A reaction of cyclopropanediazonium ion, generated by decomposition of N-cyclopropyl-N-nitrosourea upon treatment with potassium or cesium carbonates, with various poly-hydroxyarenes and aminophenols has been studied. The reaction of azo-coupling proceeds with phloroglucinol, resorcinol, 3-methoxy- and 3-aminophenol giving rise to mono-, bis-, and tris(cyclopropylazo)arenes as the major products. Oxidizable phenols such as hydro-quinone, 2-methoxy-, 4-amino-, and 2-aminophenol give products of radical transformations with participation of cyclopropyl radical.

DEBROMINATION OF 1,1-BIS(BROMOMETHYL)CYCLANES

Slobodin, Ya.M.

, p. 459 - 461 (2007/10/02)

It was shown that the composition of the debromination products from 1,1-bis(bromomethyl)cyclanes depends on the strain energy of the initial ring.
