Check Digit Verification of cas no

The CAS Registry Mumber 196618-04-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,6,6,1 and 8 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 196618-04:
(8*1)+(7*9)+(6*6)+(5*6)+(4*1)+(3*8)+(2*0)+(1*4)=169
169 % 10 = 9
So 196618-04-9 is a valid CAS Registry Number.

Intramolecular Diels-Alder reaction of chiral, highly oxygenated trienoates derived from sugar allytins

Jarosz, Slawomir,Kozlowska, Elzbieta,Jezewski, Artur

, p. 10775 - 10782 (2007/10/03)

The Lewis acid catalyzed intramolecular Diels-Alder reaction of sugar derived trienoates 3 led preferably to bicyclic endo-adducts 4. The best stereoselectivity was observed for cyclization of the L-arabino-trienoate 3b, in which only one isomer (trans) was formed. High pressure (15 kbar) cycloaddition of 3a, 3b, and 3c, led to single stereosiomers 4a, 4b, and 4c in good yields. Conversion of adduct 4a to chiral cyclopentanes was described.
