Check Digit Verification of cas no

The CAS Registry Mumber 197862-43-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,8,6 and 2 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 197862-43:
(8*1)+(7*9)+(6*7)+(5*8)+(4*6)+(3*2)+(2*4)+(1*3)=194
194 % 10 = 4
So 197862-43-4 is a valid CAS Registry Number.

Intramolecular Diels-Alder Reactions of Thio-Substituted Dienes with Enones

Chou, Shang-Shing P.,Yu, Yu-Ju

, p. 373 - 378 (1997)

Thio-substituted dienes bearing an enone moiety were readily prepared from 3-sulfolenes, and their intramolecular Diels-Alder (IMDA) reactions were studied. Octahydronaphthalenones were produced in good yield with high stereoselectivity. Hexahydroindenones were also obtained, but the stereoselectivity was lower.
