Check Digit Verification of cas no

The CAS Registry Mumber 1173929-13-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,3,9,2 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1173929-13:
(9*1)+(8*1)+(7*7)+(6*3)+(5*9)+(4*2)+(3*9)+(2*1)+(1*3)=169
169 % 10 = 9
So 1173929-13-9 is a valid CAS Registry Number.

Rhenium-catalyzed regioselective alkylation of phenols

Kuninobu, Yoichiro,Matsuki, Takashi,Takai, Kazuhiko

supporting information; experimental part, p. 9914 - 9915 (2009/12/06)

(Chemical Equation Presented) Treatment of phenol derivatives with terminal alkenes in the presence of a catalytic amount of a rhenium complex, Re 2(CO)10, gave monoalkylated phenol derivatives in good to excellent yields. This reaction proceeds at the ortho- or para-position of phenols regioselectively.
