Check Digit Verification of cas no

The CAS Registry Mumber 14064-92-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,0,6 and 4 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 14064-92:
(7*1)+(6*4)+(5*0)+(4*6)+(3*4)+(2*9)+(1*2)=87
87 % 10 = 7
So 14064-92-7 is a valid CAS Registry Number.

Spirodienones. Part 2. The Synthesis of Some Heterocyclic Spirodienones by Phenolic Coupling

Coutts, Ian G. C.,Hamblin, Michael R.,Welsby, Sheila E.

, p. 493 - 497 (2007/10/02)

The oxidation with active manganese dioxide of a series of 2,4'-dihydroxydiphenyl ethers to the corresponding p-benzoquinone monoacetals (1,3-benzodioxole-2-spirocyclohexadien-4'-ones) is described; among the dienones prepared were monoacetals of nitro-p-benzoquinone and of p-fluoranil.Attempted ether formation with 2,6-di-t-butyl-4-bromophenol and either 2- or 3-methoxyphenol failed, small quantities of unsymmetric biphenyls being formed in a novel arylation reaction.A spirobenzoxazole can be prepared by oxidation of a 2,4'-dihydroxydiphenylamine.Substituent effects in the hydrolysis of derived spirodienols have been observed.
