Check Digit Verification of cas no

The CAS Registry Mumber 169129-92-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,9,1,2 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 169129-92:
(8*1)+(7*6)+(6*9)+(5*1)+(4*2)+(3*9)+(2*9)+(1*2)=164
164 % 10 = 4
So 169129-92-4 is a valid CAS Registry Number.

SYNTHESIS OF 5,8-DIHYDROXY-6,7-DIMETHOXYFLAVONES AND REVISED STRUCTURES FOR SOME NATURAL FLAVONES

, p. 1201 - 1210 (2007/10/02)

Six 5,8-dihydroxy-6,7-dimethoxyflavones and three 8-hydroxy-5,6,7-trimethoxyflavones were synthesized from 2',5'-dihydroxy-3',4',6'-trimethoxyacetophenone by adapting the selective O-alkylation and dealkylation, and the differentiation between the flavones and their isomeric 6-hydroxyflavones was clarified by 1H NMR and UV spectra.Four natural flavones proposed as 5,8-dihydroxy-6,7-dimethoxyflavones, must have other structures and three are shown to be isomeric 5,7-dihydroxy-6,8-dimethoxyflavones.A flavone, isolated from Helichrysum, is revised to the isomeric 7-hydroxy-5,6,7-trimethoxyflavone,
