Check Digit Verification of cas no

The CAS Registry Mumber 82740-93-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,7,4 and 0 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 82740-93:
(7*8)+(6*2)+(5*7)+(4*4)+(3*0)+(2*9)+(1*3)=140
140 % 10 = 0
So 82740-93-0 is a valid CAS Registry Number.

Synthesis of (+/-)-Lineatin, an Aggregation Pheromone of Trypodendron lineatum

White, James D.,Avery, Mitchell A.,Carter, J. Paul

, p. 5486 - 5489 (1982)

A regioselective synthesis of lineatin (1) was accomplished, starting from anhydromevalonolactone (8).Photochemical cycloaddition of 8 with acetylene gave the cyclobutene 9, which was converted to lactone 13 upon methylation followed by oxidation.Hydroboration-oxidation of 13 afforded a mixture of 14 and 15, from which tosylate 18 was obtained.Reduction of 18 gave the endo hemiacetal 19, which underwent an intramolecular displacement to produce 1.Isolineatin (2) was obtained by reduction of 13 to hemiacetal 20, followed by intramolecular oxymercuration with mercuric pivalate and reduction with sodium borohydride.
