Check Digit Verification of cas no

The CAS Registry Mumber 1533457-59-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,3,3,4,5 and 7 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1533457-59:
(9*1)+(8*5)+(7*3)+(6*3)+(5*4)+(4*5)+(3*7)+(2*5)+(1*9)=168
168 % 10 = 8
So 1533457-59-8 is a valid CAS Registry Number.

Ni-Catalyzed Decarboxylative Cross-Coupling of Potassium Polyfluorobenzoates with Unactivated Phenol and Phenylmethanol Derivatives

Chen, Quan,Wu, Aizhen,Qin, Shengxiang,Zeng, Meiqi,Le, Zhiping,Yan, Zhaohua,Zhang, Hua

supporting information, p. 3239 - 3244 (2018/09/10)

A Ni-catalyzed decarboxylative cross-coupling of potassium polyfluorobenzoates with unactivated phenol and phenylmethanol derivatives is described. This novel transformation provides a practical and efficient protocol towards the synthesis of important polyfluorobiaryls and polyfluorinated diarylmethanes, and greatly enlarges the range of electrophiles utilized in decarboxylative coupling. Remarkably, preliminary mechanistic studies indicated the essential role of Zn(OAc)2 might lie in the enhancement of decarboxylation step. (Figure presented.).
