145728-45-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145728-45-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,7,2 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 145728-45:
(8*1)+(7*4)+(6*5)+(5*7)+(4*2)+(3*8)+(2*4)+(1*5)=146
146 % 10 = 6
So 145728-45-6 is a valid CAS Registry Number.

A Practical Cyclopropanation Method using Direct Generation of Organozinc Carbenoids from Carbonyl Compounds
Motherwell, William B.,Roberts, Lee R.
, p. 1582 - 1583 (2007/10/02)
A variety of readily available aryl and α,β-unsaturated carbonyl compounds, on treatment with zinc and 1,2-bis(chlorodimethylsilyl)ethane, afforded organozinc carbenoids which may be trapped with alkenes to give cyclopropanes.
