Check Digit Verification of cas no

The CAS Registry Mumber 1240781-41-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,7,8 and 1 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1240781-41:
(9*1)+(8*2)+(7*4)+(6*0)+(5*7)+(4*8)+(3*1)+(2*4)+(1*1)=132
132 % 10 = 2
So 1240781-41-2 is a valid CAS Registry Number.

Stereoselective syntheses of trisubstituted olefins via platinum catalysis: α-Silylenones with geometrical complementarity

Rooke, Douglas A.,Ferreira, Eric M.

supporting information; experimental part, p. 11926 - 11928 (2010/11/16)

The stereoselective syntheses of α-silylenones using catalytic PtCl2 are reported. Via alkyne activation, α- hydroxypropargylsilanes are converted to (Z)-silylenones through a highly selective silicon migration. The complementary (E)-silylenone
