164468-30-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 164468-30-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,4,4,6 and 8 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 164468-30:
(8*1)+(7*6)+(6*4)+(5*4)+(4*6)+(3*8)+(2*3)+(1*0)=148
148 % 10 = 8
So 164468-30-8 is a valid CAS Registry Number.

Stereoselective synthesis of enantiopure β,γ-disubstituted α-alkylidene-γ-butyrolactones via a palladium(II) catalyzed cyclization
Zhu,Lu
, p. 345 - 348 (1995)
β,γ-disubstituted α-alkylidene-γ-butyrolactones with cis or trans relative configurations were synthesized in both optically active forms from readily available homochiral allylic 2-alkynoates by Pd(II) catalysis in the presence of CuX2 and LiX.
