Check Digit Verification of cas no

The CAS Registry Mumber 344442-69-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,4,4 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 344442-69:
(8*3)+(7*4)+(6*4)+(5*4)+(4*4)+(3*2)+(2*6)+(1*9)=139
139 % 10 = 9
So 344442-69-9 is a valid CAS Registry Number.

Composes heterocycliques spiranniques. V. Synthese et etude configurationnelle dans la serie de l'oxa-2 spirodecane

Picard, Philippe,Moulines, Jean,Lecoustre, Max

, p. 65 - 70 (2007/10/02)

The 8-t-butyl-2-oxaspirodecan-3-one, 8-t-butyl-2-oxaspirodecane and its 3-methylated derivatives were synthesized by different routes starting from methyl 4-t-butylcyclohexanecarboxylate, 4-t-butylmethylenecyclohexane and methyl 4-t-butylcyclohexylidenecyanoacetate.The cis (-CH2O axial) and trans (-CH2O equatorial) isomers were isolated by preparative HPLC ; their configurations were established from (1) the known stereoselectivity of the reaction involved in the cis/trans ratio controlling step (2) their proton and 13C nmr spectra.
