Check Digit Verification of cas no

The CAS Registry Mumber 2544-45-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,4 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2544-45:
(6*2)+(5*5)+(4*4)+(3*4)+(2*4)+(1*5)=78
78 % 10 = 8
So 2544-45-8 is a valid CAS Registry Number.

Rhodium-catalyzed P-P bond exchange reaction of diphosphine disulfides

Arisawa, Mieko,Yamada, Tomoki,Tanii, Saori,Kawada, Yuta,Hashimoto, Hisako,Yamaguchi, Masahiko

supporting information, p. 13580 - 13583 (2016/11/25)

A rhodium-catalyzed exchange reaction of diphosphine disulfides, a diphosphine oxide, and a diphosphine is developed. Various symmetric diphosphine disulfides containing alkyl and phenyl groups are exchanged, giving equilibrium mixtures, from which unsymmetric diphosphine disulfides are readily separated by silica gel chromatography. The resulting unsymmetric diphosphine disulfide is regioselectively added to an aldehyde.
