Check Digit Verification of cas no

The CAS Registry Mumber 141611-64-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,6,1 and 1 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 141611-64:
(8*1)+(7*4)+(6*1)+(5*6)+(4*1)+(3*1)+(2*6)+(1*4)=95
95 % 10 = 5
So 141611-64-5 is a valid CAS Registry Number.

Synthesis and Some Properties of D-myo-Inositol 1,4,5-Tris(dihydrogen phosphate)

Ozaki, Shoichiro,Kondo, Yoshihisa,Shiotani, Naokazu,Ogasawara, Tomio,Watanabe, Yutaka

, p. 729 - 738 (2007/10/02)

Optically active myo-inositol 1,4,5-tris(dihydrogen phosphate) 1, which has now been recognized as a second messenger in a new intracellular signal transduction system, has been prepared starting from myo-inositol.The key step, phosphorylation of an adequately protected polyhydroxy derivative, was accomplished by three methods, among which a phosphoramidite method using a new phosphitylating agent, o-xylylene N,N-diethylphosphoramidite, gave the triphosphoric ester in quantitative yield.Optical resolution was effectively realized by derivatization into diastereoisomeric l-menthoxyacetic esters.NMR spectra and optical rotation are shown to depend on the pH of an aqueous solution of compound 1.
