Check Digit Verification of cas no

The CAS Registry Mumber 201160-28-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,1,6 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 201160-28:
(8*2)+(7*0)+(6*1)+(5*1)+(4*6)+(3*0)+(2*2)+(1*8)=63
63 % 10 = 3
So 201160-28-3 is a valid CAS Registry Number.

Sodium-Ketyl Radical Anions by Reverse Pinacol Reaction and Their Coupling with Iodoarenes

Tang, Xinjun,Studer, Armido

supporting information, p. 4448 - 4450 (2016/11/07)

Transition-metal-free C-C bond formation between aryl iodides and pinacols is presented. Pinacols are readily transformed by deprotonation with NaH to their Na-pinacolates. C-C-bond homolysis at room temperature generates in situ the corresponding Na-ketyl radical anions which react with various aryl iodides in a homolytic aromatic substitution reaction to form tertiary Na-alcoholates. Protonation eventually provides tertiary alcohols in an unprecedented route.
