Check Digit Verification of cas no

The CAS Registry Mumber 243140-10-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,3,1,4 and 0 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 243140-10:
(8*2)+(7*4)+(6*3)+(5*1)+(4*4)+(3*0)+(2*1)+(1*0)=85
85 % 10 = 5
So 243140-10-5 is a valid CAS Registry Number.

Structure and spectroscopic characteristics of 2'-diethylboryl-4''- dimethylaminochalcone bearing an intramolecular boron-oxygen coordinate bond

Murafuji,Sugihara,Moriya,Mikata,Yano

, p. 683 - 685 (1999)

How formation of an intramolecular coordinate bond affects the molecular structure was examined in the structural comparison of 2'-diethylboryl-4''- dimethylaminochalcone (1) and 2'-ethylenedioxyboryl-4''-dimethylaminochalcone (2) with chloro-{2-[(4-dimethylaminostyryl) carbonyl] phenyl} (4-methyl- phenyl)] bismuthane (3) and 4''-dimethylaminochalcone (4).
