142631-00-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 142631-00-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,6,3 and 1 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 142631-00:
(8*1)+(7*4)+(6*2)+(5*6)+(4*3)+(3*1)+(2*0)+(1*0)=93
93 % 10 = 3
So 142631-00-3 is a valid CAS Registry Number.

Practical synthesis of all inositol stereoisomers from myo-inositol

Chung, Sung-Kee,Kwon, Yong-Uk

, p. 2135 - 2140 (2007/10/03)

Synthesis of six inositol stereoisomers was successfully carried out via conduritol intermediates prepared from myo-inositol. Dihydroxylation and epoxidation followed by ring opening of the conduritol B, C and F derivatives gave epi-, allo-, muco-, neo-, DL-chiro- and scyllo-inositol. The cis- inositol derivative, which may not be prepared by this approach, was synthesized in 5 steps via 2-O-benzoyl-myo-inositol orthoformate as the key intermediate.

Efficient and systematic syntheses of enantiomerically pure and regiospecifically protected myo-inositols

Bruzik, Karol S.,Tsai, Ming-Daw

, p. 6361 - 6374 (2007/10/02)

Efficient and systematic syntheses of a variety of enantiomerically pure and regiospecifically protected myo-inositols, which can be readily used as precursors for most natural and unnatural derivatives of myo-inositol, have been developed. The key strate
