Check Digit Verification of cas no

The CAS Registry Mumber 77302-56-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,3,0 and 2 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 77302-56:
(7*7)+(6*7)+(5*3)+(4*0)+(3*2)+(2*5)+(1*6)=128
128 % 10 = 8
So 77302-56-8 is a valid CAS Registry Number.

Page/Page column 7, (2012/12/13)

A solid ink composition comprising an amorphous component, a crystalline material, and optionally, a colorant, which are suitable for ink jet printing, including printing on coated paper substrates, and methods for making the same. In embodiments, the crystalline and amorphous components are synthesized from an esterification reaction of tartaric acid with an alcohol.

2-Chloro-(4R,5R)-bis[(1R,2S,5R)-menth-1-yloxycarbonyl]-1,3, 2-dioxaphospholane: A practical chiral pool-derived reagent for determining enantiomeric purity of alcohols

, p. 3907 - 3910 (2008/09/20)

(Chemical Equation Presented) 2-Chloro-(4R,5R)-bis[(1R,2S,5R)-menth-1- yloxycarbonyl)]-1,3,2-dioxaphospholane is a practical reagent for reliably determining enantiomeric purity of chiral alcohols via 31P NMR spectroscopy. The compound is available as a crystalline solid on a 20 g scale from PCl3 and bis[(1R,2S,5R)-menth-1-yl] tartrate. It is comparatively inert toward spontaneous hydrolysis under conventional laboratory conditions but undergoes quantitative substitution of alkoxide for chloride if treated with a chiral alcohol. Nonequivalent 31P NMR signals of diastereomeric 2-alkoxy-1,3,2-dioxophospholanes were dispersed by ~1.4-0.1 ppm. The associated integral ratios reflected enantiomeric purities of preweighted samples of (R)- and (S)-1-phenylethanol, (+)- and (-)-menthol, and a set of primary, secondary, and tertiary alcohols with a precision of ±0.4-1.0%.
