Check Digit Verification of cas no

The CAS Registry Mumber 109057-56-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,0,5 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 109057-56:
(8*1)+(7*0)+(6*9)+(5*0)+(4*5)+(3*7)+(2*5)+(1*6)=119
119 % 10 = 9
So 109057-56-9 is a valid CAS Registry Number.

A regioselective Aluminium Chloride-catalyzed Acylation of Allylic Selenides via α-Silyl Intermediates

Hiroi, Kunio,Sato, Hiroyasu

, p. 1723 - 1726 (2007/10/02)

The aluminium chloride-catalyzed acylation of α-silylallylic selenides with acid chlorides at -78 deg C produced γ-acylated vinylic selenides regioselectively. α-Silylallylic selenides in some cases underwent shifts of the selenenyl groups by the catalysis with aluminium chloride, affording γ-silylallylic selenides.This regioselective acylation of allylic selenides provides a new route to dihydrojasmone.
