145291-70-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145291-70-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,2,9 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 145291-70:
(8*1)+(7*4)+(6*5)+(5*2)+(4*9)+(3*1)+(2*7)+(1*0)=129
129 % 10 = 9
So 145291-70-9 is a valid CAS Registry Number.

Unusual ε/γ-Regiospecifity of (E/Z)-Pentadienyltin in the Lewis Acid-promoted Reaction with an Aldehyde
Nishigaichi, Yutaka,Fujimoto, Manabu,Takuwa, Akio
, p. 2581 - 2582 (2007/10/02)
In the Lewis acid-promoted reaction between pentadienyltin (PDT) and an aldehyde, (E)- and (Z)-PDTs exhibit opposite regioreactivities: (E)-PDT reacts at the terminal ε-position and (Z)-PDT at the internal γ-position.
