Check Digit Verification of cas no

The CAS Registry Mumber 1258278-95-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,2,7 and 8 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1258278-95:
(9*1)+(8*2)+(7*5)+(6*8)+(5*2)+(4*7)+(3*8)+(2*9)+(1*5)=193
193 % 10 = 3
So 1258278-95-3 is a valid CAS Registry Number.

Synthesis and comparative characterization of 9-boraanthracene, 5-boranaphthacene, and 6-borapentacene stabilized by the H2IMes carbene

Wood, Thomas K.,Piers, Warren E.,Keay, Brian A.,Parvez, Masood

supporting information; experimental part, p. 12199 - 12206 (2011/02/25)

A general procedure for the preparation of three N-heterocyclic carbene stabilized, boron-containing acenes (9-boraanthracene, 5-boranaphthacene, and 6-borapentacene) is presented. The key steps involve a transmetallation reaction between BCl3 and an appropriate stannacyclic precursor, and the dehydrochlorination of the H2IMes adduct of the chloroborane product. Comparative structural, photophysical, and redox properties reveal narrow HOMO-LUMO gaps relative to the all-carbon acene analogues. Just add boron: Synthetic routes to the N-heterocyclic-carbene-stabilized 5-boranaphthacene and 6-borapentacene are described and complement that previously developed for 9-boraanthracene. Comparative structural, photophysical, and redox properties reveal narrow HOMO-LUMO gaps relative to the all-carbon acene analogues.
