Check Digit Verification of cas no

The CAS Registry Mumber 107741-13-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,7,4 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 107741-13:
(8*1)+(7*0)+(6*7)+(5*7)+(4*4)+(3*1)+(2*1)+(1*3)=109
109 % 10 = 9
So 107741-13-9 is a valid CAS Registry Number.

A novel entry to naturally occurring 5-alkenyl α,β-unsaturated δ-lactones from D-glucose: Syntheses of (+)-acetylphomalactone and (+)-asperlin

Gomez, Ana M.,De Uralde, Beatrix Lopez,Valverde, Serafin,Lopez, J. Cristobal

, p. 1647 - 1648 (1997)

A bicyclic pyranosidic glycoside 6, readily obtained from D-glucose, has been used as the key intermediate in enantioselective syntheses of (+)-acetylphomalactone and (+)-asperlin, in which the configuration at C-5 corresponds to that of the hexopyranosides in the L-sugar series.

Total syntheses of (+)-asperlin, (+)-acetylphomalactone and (5S,6S,7R,8S)-asperlin based on the kinetic resolution of 2-furylmethanols

Yang, Zhi-Cai,Jiang, Xiao-Bin,Wang, Zhi-Min,Zhou, Wei-Shan

, p. 317 - 321 (2007/10/03)

The total syntheses of (+)-asperlin 1, (+)-acetylphomalactone 2 and (5S,6S,7R,8S)-asperlin 3 have been achieved employing the kinetic resolution of unsymmetric divinylmethanol using modified Sharpless reagents, which produced two oxidation products, as a

Total synthesis of (+)-Asperlin

Ramesh,Franck

, p. 137 - 140 (2007/10/02)

A stereochemically unambiguous synthesis of (+)-asperlin from L-rhamnose establishes the configuration of the antibiotic as 4S, 5S, 6S, 7R.
