Check Digit Verification of cas no

The CAS Registry Mumber 15271-51-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,2,7 and 1 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 15271-51:
(7*1)+(6*5)+(5*2)+(4*7)+(3*1)+(2*5)+(1*1)=89
89 % 10 = 9
So 15271-51-9 is a valid CAS Registry Number.

A C 2-symmetric chiral pool-based flexible strategy: Synthesis of (+)- and (-)-shikimic acids, (+)- and (-)-4- epi -shikimic acids, and (+)- and (-)-pinitol

Ananthan, Bakthavachalam,Chang, Wan-Chun,Lin, Jhe-Sain,Li, Pin-Hui,Yan, Tu-Hsin

, p. 2898 - 2905 (2014)

Via combination of a novel acid-promoted rearrangement of acetal functionality with the controlled installation of the epoxide unit to create the pivotal epoxide intermediates in enantiomerically pure form, a simple, concise, flexible, and readily scalable enantiodivergent synthesis of (+)- and (-)-shikimic acids and (+)- and (-)-4-epi-shikimic acids has emerged. This simple strategy not only provides an efficient approach to shikimic acids but also can readily be adopted for the synthesis of (+)- and (-)-pinitols. These concise total syntheses exemplify the use of pivotal allylic epoxide 14 and its enantiomer ent-14. A readily available inexpensive C2-symmetric l-tartaric acid (7) served as key precursor. In general, the strategy here provides a neat example of the use of a four-carbon chiron and offers a good account of the synthesis of functionalized cyclohexane targets.

(1E,3E)-4-acetoxy-1-phenyldimethylsilyl-1,3-butadiene as a surrogate for (1E,3E)-1,4-diacetoxy-1,3-butadiene: A highly coefficient synthesis of (±)-shikimic acid

Koreeda,Teng,Murata

, p. 5997 - 6000 (2007/10/02)

The 5-step synthesis of (±)-shikimic acid has been achieved in 55% overall yield from (1E,3E)-4-acetoxy-1-phenyldimethylsilyl-1,3-butadiene, starting with its Diels-Alder reaction with 2-(trimethylsilyl)ethyl acrylate and featuring the use of Fleming's on

SHIKIMIC ACIDS FROM FURAN; METHODS OF STEREOCONTROLLED ACCESS TO 3,4,5-TRIOXIGENATED CYCLOHEXENES

Rajapaksa, D.,Keay, B. A.,Rodrigo, R.

, p. 826 - 828 (2007/10/02)

Oxabicycloheptenes 1 and 2 are converted to 3,4,5-oxigenated cyclohexenes by stereocontrolled hydroxylations and epoxidations coupled with reverse-Michael cleavage of the oxabicyclo system.Three epimers of shikimic acid are synthesized by these methods.
