Check Digit Verification of cas no

The CAS Registry Mumber 62498-93-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,4,9 and 8 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 62498-93:
(7*6)+(6*2)+(5*4)+(4*9)+(3*8)+(2*9)+(1*3)=155
155 % 10 = 5
So 62498-93-5 is a valid CAS Registry Number.

SYNTHESIS OF FLEXIBILENE, A NATURALLY OCCURING 15-MEMBERED-RING DITERPENE

McMurry, John,Matz, James R.,Kees, Kenneth L.,Bock, Peter A.

, p. 1777 - 1780 (1982)

A total synthesis of the naturally occuring 15-membred ring diterpene, flexibilene, was accomplished using a titanium-induced cyclization of the keto-aldehyde 3,3,7,11-tetramethyl-15-oxohexadeca-4E,7E,11E-trienal as the key step.

Synthesis of Macrocyclic Terpenoids by Intramolecular Carbonyl Coupling: Flexibilene and Humulene

McMurry, John E.,Matz, James R.,Kees, Kenneth L.

, p. 5489 - 5498 (2007/10/02)

Total syntheses of two macrocyclic sesquiterpene hydrocarbons, humulene (1) and flexibilene (2) are discussed in detail.Both were prepared in high overall yield by titanium-induced cyclization of the appropriate keto aldehyde precursors (4 and 9, respectively), themselves obtained by coupling of the vinylic zirconium reagent 22 with pi-allylpalladiums 26 and 23.
