Check Digit Verification of cas no

The CAS Registry Mumber 1237745-23-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,7,7,4 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1237745-23:
(9*1)+(8*2)+(7*3)+(6*7)+(5*7)+(4*4)+(3*5)+(2*2)+(1*3)=161
161 % 10 = 1
So 1237745-23-1 is a valid CAS Registry Number.

Synthesis of functionalizable boron-containing π-electron materials that incorporate formally aromatic fused borepin rings

Caruso Jr., Anthony,Siegler, Maxime A.,Tovar, John D.

, p. 4213 - 4217 (2010)

(Figure Presented) Not a natty B-OH: Borepin-based extended π-electron molecules contain bulky substituents that shield the vacant boron p orbitals and allow synthetic manipulation and purification under ambient conditions. These borepin-containing compounds (see picture; Mes* = 1,3,5-tris(tert-butyl) phenyl; B orange, C gray) display reversible cathodic electrochemistry and can be viewed as n-type analogues to bent acene hydrocarbons.
