Check Digit Verification of cas no

The CAS Registry Mumber 1382763-56-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,2,7,6 and 3 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1382763-56:
(9*1)+(8*3)+(7*8)+(6*2)+(5*7)+(4*6)+(3*3)+(2*5)+(1*6)=185
185 % 10 = 5
So 1382763-56-5 is a valid CAS Registry Number.

Synthesis of a class of binaphthyl monophosphine ligands with a naphthofuran skeleton and their applications in Suzuki-Miyaura coupling reactions

Zhou, Zihong,Liang, Hao,Xia, Wang,Chen, Huixuan,Zhang, Yaqi,He, Xuefeng,Yu, Sifan,Cao, Rihui,Qiu, Liqin

, p. 5967 - 5971 (2018)

A series of new monophosphine ligands containing a naphthofuran skeleton have been prepared, characterized and evaluated in palladium-catalyzed Suzuki-Miyaura coupling reactions. Using Pd2(dba)3-L6 as the catalyst the reactions were performed with high catalytic activity under mild reaction conditions and the desired coupling products were obtained in good to excellent yields. The new catalyst system also showed broad substrate adaptability and practicality for gram-scale production.

Anionic phospho-fries rearrangement at ferrocene: One-pot approach to P,O-substituted ferrocenes

Korb, Marcus,Schaarschmidt, Dieter,Lang, Heinrich

supporting information, p. 2099 - 2108 (2014/05/20)

For the first time the anionic phospho-Fries rearrangement has been successfully applied in ferrocene chemistry, giving access to 1,2-P,O-substituted ferrocenes. The 1,3 (O → C)-migration occurs at ferrocenyl phosphates, thiophosphates, phosphite-borane adducts, and phosphinates by treatment with a base such as lithium diisopropylamide at low temperature, whereas the highest yields were obtained starting from diethylferrocenyl phosphate. Complete reduction of the phosphonate to a primary phosphine and subsequent Stelzer P,C cross coupling allowed the synthesis of Fe(η5-C5H3-2-OMe-PPh2) (η5-C5H5) (1). The qualification of 1 as a supporting ligand in palladium-catalyzed Suzuki-Miyaura C,C couplings has been proven by the synthesis of sterically congested tri-ortho-substituted biaryls under mild reaction conditions in good to excellent yields.
