Check Digit Verification of cas no

The CAS Registry Mumber 53174-37-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,1,7 and 4 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 53174-37:
(7*5)+(6*3)+(5*1)+(4*7)+(3*4)+(2*3)+(1*7)=111
111 % 10 = 1
So 53174-37-1 is a valid CAS Registry Number.

Cyclopentadienylidenephosphinazines

Freeman,Lloyd,Singer

, p. 211 - 216 (2007/10/13)

Diazocyclopentadienes which are not alkyl- or aryl-substituted at both the 2- and 5-positions react readily with triphenylphosphine to form cyclopentadienylidenephosphinazines. If both of these positions are so substituted phosphinazines are not formed. A phosphinazine was obtained from 2-chloro-3,4,5-triphenyldiazocyclopentadiene while its 2-nitro-analogue apparently formed a readily hydrolysed phosphinazine. Diazotetraphenylcyclopentadiene formed a phosphinazine with tri-n-butylphosphine. The reasons for these differences in reactivity are discussed. When heated to higher temperatures some of the phosphinazines decomposed with loss of nitrogen to give phosphonium cyclopentadienylides. Electron-withdrawing substituents in the five-membered ring make the phosphinazines susceptible to ready hydrolysis to cyclopentadienone hydrazones. Cyclopentadienylidenephosphinazines are protonated by mineral acids on nitrogen rather than on the cyclopentadiene ring.
