Check Digit Verification of cas no

The CAS Registry Mumber 6682-06-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,8 and 2 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6682-06:
(6*6)+(5*6)+(4*8)+(3*2)+(2*0)+(1*6)=110
110 % 10 = 0
So 6682-06-0 is a valid CAS Registry Number.

Palladium-catalyzed benzannulation from alkynes and allylic compounds

Tsukada, Naofumi,Sugawara, Shuichi,Nakaoka, Keiichiro,Inoue, Yoshio

, p. 5961 - 5966 (2007/10/03)

Various alkynes reacted with allyl tosylates in the presence of palladium catalysts, giving polysubstituted benzenes with good to high regioselectivity. Pentasubstituted and trisubstituted benzenes were readily prepared by reaction of internal alkynes and
