Check Digit Verification of cas no

The CAS Registry Mumber 72018-83-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,0,1 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 72018-83:
(7*7)+(6*2)+(5*0)+(4*1)+(3*8)+(2*8)+(1*3)=108
108 % 10 = 8
So 72018-83-8 is a valid CAS Registry Number.

DERIVATE DES PHOSPHORSAEURE-o-PHENYLENESTERS. 20. Halogenierung von aromatischen o-Phenylenphosphiten. Ein Gleichgewicht zwischen Phosphonium- und Phosphoranstruktur

Gloede, Joerg,Gross, Hans,Michalski, Jan,Pakulski, Marek,Skowronska, Aleksandra

, p. 157 - 162 (2007/10/02)

The halogenation of phenyl- and o-methoxyphenyl-o-phenylene phosphites (1b,1c) gives at low temperature pentacoordinated dihalogenophosphoranes 4a, 4b, 5a, 5b.They are stable at room temperature with the exception of 5b.Even at -100 deg C 5b slowly gives a bromospirophosphorane 3b by breaking the ether linkage.The primary formed phosphorane is in an equilibrium with the phosphoniumsalt; both phosphorus compounds are proved with 31P n.m.r. spectroscopy.
