Check Digit Verification of cas no
The CAS Registry Mumber 1297599-05-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,7,5,9 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1297599-05:
(9*1)+(8*2)+(7*9)+(6*7)+(5*5)+(4*9)+(3*9)+(2*0)+(1*5)=223
223 % 10 = 3
So 1297599-05-3 is a valid CAS Registry Number.

Site-selective arylation of alizarin and purpurin based on Suzuki-Miyaura cross-coupling reactions
Mahal, Ahmed,Villinger, Alexander,Langer, Peter
, p. 2075 - 2087 (2011)
A variety of arylated anthraquinones were prepared by site-selective Suzuki-Miyaura cross-coupling reactions of the bis- and tris(triflates) of alizarin and purpurin, respectively. The site-selectivity is controlled by the electronic influence of the carb
