Check Digit Verification of cas no

The CAS Registry Mumber 20764-34-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,7,6 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 20764-34:
(7*2)+(6*0)+(5*7)+(4*6)+(3*4)+(2*3)+(1*4)=95
95 % 10 = 5
So 20764-34-5 is a valid CAS Registry Number.

Chemistry of the 2-Pinanols. 2. Investigation of the Utility of the Enhanced Basicities of the Pinanoxide Bases

Traynor, Sean G.,Kane, Bernard J.,Coleman, Jacquelyn B.,Cardenas, Carlos G.

, p. 900 - 906 (1980)

The utility of the alkoxides of cis- and trans-2-pinanol has been investigated.Yiels comparable to and exceeding those obtained with tert-butoxide are reported for the alkylation of ethyl acetoacetate, for the conversion of α-pinene oxide to trans-pinocarveol and cis-3-pinen-2-ol, and for the isomerization of vinylnorbornene and limonene.Dehydrohalogenation was effected rapidly on bornyl chloride and 2,6-dichlorocamphane-compounds reported to be inert to potassium tert-butoxide in tert-butyl alcohol.Reactions with 1-octyl bromide and with benzyl chloride showed that the pinanoxides have nucleophilicities comparable to that of tert-butoxide.
