Check Digit Verification of cas no

The CAS Registry Mumber 1232138-96-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,2,1,3 and 8 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1232138-96:
(9*1)+(8*2)+(7*3)+(6*2)+(5*1)+(4*3)+(3*8)+(2*9)+(1*6)=123
123 % 10 = 3
So 1232138-96-3 is a valid CAS Registry Number.

Preparation of benzylphosphonates via a palladium(0)-catalyzed cross-coupling of H-phosphonate diesters with benzyl halides. Synthetic and mechanistic studies

Laven, Gaston,Kalek, Marcin,Jezowska, Martina,Stawinski, Jacek

, p. 967 - 975 (2010)

We have developed a new, efficient method for the synthesis of benzylphosphonate and benzylphosphonothioate diesters via a palladium(0)- catalyzed cross-coupling reaction between benzyl halides and H-phosphonate or H-phosphonothioate diesters, using Pd2(dba)3(CHCl 3) as a palladium source and Xantphos as a supporting ligand. Some mechanistic aspects of these reactions were investigated using 31P NMR spectroscopy.
