Check Digit Verification of cas no

The CAS Registry Mumber 1438770-06-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,8,7,7 and 0 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1438770-06:
(9*1)+(8*4)+(7*3)+(6*8)+(5*7)+(4*7)+(3*0)+(2*0)+(1*6)=179
179 % 10 = 9
So 1438770-06-9 is a valid CAS Registry Number.

Regioselective synthesis of multisubstituted benzenes by palladium-catalyzed intermolecular reaction of β-iodo-β-silylstyrenes with alkynes

Kinoshita, Hidenori,Takahashi, Hirotoshi,Miura, Katsukiyo

, p. 2962 - 2965 (2013/07/26)

The Pd-catalyzed reaction between β-iodo-β-silylstyrenes and terminal alkynes in i-Pr2NEt gave 1,2,3,5-tetrasubstituted benzenes with complete regioselection. The use of certain silylacetylenes as alkynes enabled efficient synthesis of 1,3,5-trissilyl-2-arylbenzenes, which could be transformed into other multisubstituted benzenes by displacement of the silyl groups.
