Check Digit Verification of cas no

The CAS Registry Mumber 128851-19-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,8,5 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128851-19:
(8*1)+(7*2)+(6*8)+(5*8)+(4*5)+(3*1)+(2*1)+(1*9)=144
144 % 10 = 4
So 128851-19-4 is a valid CAS Registry Number.

Syntheses und NMR-Spektren phosphororganischer Antioxidantien und verwandter Verbindungen

Koenig, T.,Habicher, W.D.,Haehner, U.,Pionteck, J.,Rueger, C.,Schwetlick, K.

, p. 333 - 349 (2007/10/02)

The syntheses of various aliphatic, aromatic, sterically hindered, and cyclic organophosphorus compounds (phosphorous acid esters, esters chlorides and ester amides, hydrogen phosphites, phosphinates and phosphates) are reported, and general procedures for preparation are given.The compounds synthesized were investigated by means of 31P-, 1H- and 13C-n.m.r. spectroscopy, and the chemical shifts measured are listed.
