Check Digit Verification of cas no

The CAS Registry Mumber 153381-08-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,3,8 and 1 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 153381-08:
(8*1)+(7*5)+(6*3)+(5*3)+(4*8)+(3*1)+(2*0)+(1*8)=119
119 % 10 = 9
So 153381-08-9 is a valid CAS Registry Number.

Phlenumdines A?C, New lycopodium alkaloids isolated from phlegmariurus nummulariifolius

Nakayama, Waka,Monthakantirat, Orawan,Fujikawa, Kazumi,Watthana, Santi,Kitanaka, Susumu,Makino, Toshiaki,Ishiuchi, Kanichiro

, p. 2247 - 2261 (2017)

Three new lycopodine-type alkaloids, phlenumdines A?C (1?3), have been isolated from the clubmoss Phlegmariurus nummulariifolius (Blume) Ching, and their structures were elucidated on the basis of spectroscopic data.

Total synthesis of (+)-pentamethylsalvianolic acid C

Alford, Benjamin L.,Huegel, Helmut M.

supporting information, p. 2724 - 2727 (2013/06/04)

The total synthesis of a methylated analogue of (+)-Salvianolic acid C has been achieved. Key aspects of the synthetic route include an economical Cu(i) acetylide coupling, unique carboxyl activation conditions via microwave irradiation and a novel lipase catalysed kinetic resolution of a racemic mixture of secondary alcohol Danshensu. The preparation of this methylated analogue will not only improve the bioavailability, but also enable access to new and wider bioactivity applications for (+)-Salvianolic acid C.

Tricyclic benzomorphan analogues by intramolecular Oxa-Pictet-Spengler reaction

Wunsch,Zott

, p. 2307 - 2310 (2007/10/02)

The key step in the regio- and stereoselective preparation of the benzomorphan analogues 9, 10a, 10b, 14 and 15 is an intramolecular Oxa-Pictet-Spengler reaction. Masked as an acetal the carbonyl component is connected via an amide to the 2-phenylethanol component (7, 12).
