Check Digit Verification of cas no

The CAS Registry Mumber 89767-23-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,7,6 and 7 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 89767-23:
(7*8)+(6*9)+(5*7)+(4*6)+(3*7)+(2*2)+(1*3)=197
197 % 10 = 7
So 89767-23-7 is a valid CAS Registry Number.

Cyclotetra((λ3-phosphazanes) derivant de diamines-1,2. Precurseurs de composes du phosphore dicoordonne

Malavaud, Christian,N'Gando M'Pondo, Teophile,Lopez, Lucien,Barrans, Jean,Legros, Jean-Pierre

, p. 43 - 50 (2007/10/02)

Cyclotetraphosphazanes 2 and 5 obtained from 1,2-diamines are 1,3,2-diazaphosphole oligomers leading to the monomeric form by either thermal equilibrium or by complexing with boron trifluoride.The dicoordinated form stabilized by an orthophenylene ring could explain the reactivity of 4,5-benzo 1,3,2-diazaphosphole 3 with compounds having a mobile hydrogen; these reactions were a 1.2 type addition while butanol led to a 1.1 type addition with complexed 1,3,2-diazaphospholes 4 and 8.
