Check Digit Verification of cas no

The CAS Registry Mumber 442913-72-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,2,9,1 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 442913-72:
(8*4)+(7*4)+(6*2)+(5*9)+(4*1)+(3*3)+(2*7)+(1*2)=146
146 % 10 = 6
So 442913-72-6 is a valid CAS Registry Number.

First total synthesis of pinolide

Yadav, Jhillu Singh,Avuluri, Srilatha,Kattela, Shiva Shankar,Das, Saibal

, p. 6967 - 6972 (2013)

The first total synthesis of pinolide, a nonsymmetrical ten-membered macrocyclic, is described starting from readily available (-)-tartaric and L-ascorbic acid. The key synthetic steps include Barbier allylation, Yamaguchi esterification and ring-closing metathesis (RCM) reactions. The synthetic strategy has been successful for the construction of the ten-membered core skeleton. A facile and convergent approach enabled the incorporation of all the four stereogenic centers present in the molecule. The first total synthesis of pinolide, a nonsymmetrical ten-membered macrocycle having four stereogenic centers has been demonstrated. The stereoselective approach involves key reaction steps including Barbier allylation, Yamaguchi esterification, and Grubbs' ring-closing metathesis reactions. Copyright

Total synthesis and evaluation of the actin-binding properties of microcarpalide and a focused library of analogues

Fuerstner, Alois,Nagano, Takashi,Mueller, Christoph,Seidel, Guenter,Mueller, Oliver

, p. 1452 - 1462 (2008/02/04)

A comparative investigation shows that hydroxylated 10-membered lactones modeled around the fungal metabolites microcarpalide (1) and pinolidoxin (2) are endowed with selective actin-binding properties. Although less potent than the marine natural product
