Check Digit Verification of cas no
The CAS Registry Mumber 19934-95-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,3 and 4 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 19934-95:
(7*1)+(6*9)+(5*9)+(4*3)+(3*4)+(2*9)+(1*5)=153
153 % 10 = 3
So 19934-95-3 is a valid CAS Registry Number.

Nowrouzi, Najmeh,Keshtgar, Saba,Bahman Jahromi, Enayatollah
, p. 348 - 350 (2016/01/12)
A reusable ligand-free palladium catalyzed phosphorylation of aryl iodides using PdCl2/tetrabutylammonium bromide is described. Functionalized triarylphosphines were obtained in good to excellent yields in the absence of external reductants and supporting ligands.
