Check Digit Verification of cas no

The CAS Registry Mumber 178491-63-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,4,9 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 178491-63:
(8*1)+(7*7)+(6*8)+(5*4)+(4*9)+(3*1)+(2*6)+(1*3)=179
179 % 10 = 9
So 178491-63-9 is a valid CAS Registry Number.

Cyclophosphorylation of polyphenols by diamidoarylphosphites

Maslennikova, Vera I.,Merkulov, Roman V.,Dyagileva, Maria V.,Vasyanina, Larisa K.,Lyssenko, Konstantin A.,Antipin, Mikhail Yu.,Weber, Dirk,Bauer, Ingmar,Habicher, Wolf D.,Nifantyev, Eduard E.

, p. 1753 - 1761 (2007/10/03)

It was found that the cyclophosphorylation of polyphenols by diamidoarylphosphites proceeds via the rupture of only one P-N bond and one P-O bond, the second P-N bond remaining intact. It is supposed that the unusual lack of reactivity of the P-N bond is due to the spatial arrangement of the amido group with respect to the reaction site in phosphorylated intermediates 5.
