Check Digit Verification of cas no
The CAS Registry Mumber 156518-26-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,5,1 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 156518-26:
(8*1)+(7*5)+(6*6)+(5*5)+(4*1)+(3*8)+(2*2)+(1*6)=142
142 % 10 = 2
So 156518-26-2 is a valid CAS Registry Number.

A 1,2-Silicon Shift in Cyclopropylidenes leading to 1-Trialkylsilylcyclopropenes
Baird, Mark S.,Dale, Cynthia M.,Dulayymi, Juma'a R. Al
, p. 1373 - 1374 (1993)
1,1-Dibromo-2-trialkylsilylcyclopropanes, readily prepared by dibromocyclopropanation of vinyltrialkylsilanes, react with methyllithium at -90 to 20 deg C to give high yields of trialkylsilylcyclopropenes in which the silicon has apparently migrated to C-1.
