Check Digit Verification of cas no

The CAS Registry Mumber 1254205-40-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,4,2,0 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1254205-40:
(9*1)+(8*2)+(7*5)+(6*4)+(5*2)+(4*0)+(3*5)+(2*4)+(1*0)=117
117 % 10 = 7
So 1254205-40-7 is a valid CAS Registry Number.

Design and synthesis of novel molecular tweezer anion receptors based on diphenic acid carbonyl thiosemicarbazide

Li, Xiaorui,Zhao, Zhigang,Li, Guohua,Shi, Peiyu

body text, p. 410 - 413 (2010/12/19)

Ten novel molecular tweezer anion receptors based on diphenic acid carbonyl thiosemicarbazide have been designed and synthesised in high yield and their binding properties were examined by UV-Vis spectra titration. Their structures were characterised by 1H NMR, IR, MS spectra and elemental analysis.
