128445-91-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128445-91-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,4,4 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 128445-91:
(8*1)+(7*2)+(6*8)+(5*4)+(4*4)+(3*5)+(2*9)+(1*1)=140
140 % 10 = 0
So 128445-91-0 is a valid CAS Registry Number.

Experiments Concerning the Reactions of Benzocyclopropene under Yb(fod)3 Catalysis
Neidlein, Richard,Kraemer, Bettina
, p. 353 - 356 (2007/10/02)
1,3-Dihydroisobenzofuran derivatives 3a-e and 5a-c are obtained by reactions of α,β-unsaturated carbonyl compounds with benzocyclopropene (1).The yields increase by addition of Yb(fod)3.Aromatic aldehydes react in the same way.Yb(fod)3 has no influence on
