Check Digit Verification of cas no

The CAS Registry Mumber 1631035-62-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,1,0,3 and 5 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1631035-62:
(9*1)+(8*6)+(7*3)+(6*1)+(5*0)+(4*3)+(3*5)+(2*6)+(1*2)=125
125 % 10 = 5
So 1631035-62-5 is a valid CAS Registry Number.

Nickel-Catalyzed Reductive Cross-Coupling of Aryl Halides with Monofluoroalkyl Halides for Late-Stage Monofluoroalkylation

Sheng, Jie,Ni, Hui-Qi,Zhang, Hao-Ran,Zhang, Kai-Fan,Wang, Yi-Ning,Wang, Xi-Sheng

supporting information, p. 7634 - 7639 (2018/06/26)

A combinatorial nickel-catalyzed monofluoroalkylation of aryl halides with unactivated fluoroalkyl halides by reductive cross-coupling has been developed. This method demonstrated high efficiency, mild conditions, and excellent functional-group tolerance, thus enabling the late-stage monofluoroalkylation of diverse drugs. The key to success was the combination of diverse readily available bidentate and monodentate pyridine-type nitrogen ligands with nickel, which in situ generated a variety of readily tunable catalysts to promote fluoroalkylation with broad scope with respect to both coupling partners. This combinatorial catalysis strategy offers a solution for nickel-catalyzed reductive cross-coupling reactions and provides an efficient way to synthesize fluoroalkylated druglike molecules for drug discovery.
