145733-73-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145733-73-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,7,3 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 145733-73:
(8*1)+(7*4)+(6*5)+(5*7)+(4*3)+(3*3)+(2*7)+(1*3)=139
139 % 10 = 9
So 145733-73-9 is a valid CAS Registry Number.

A novel regio- and stereo-specific hydroacetoxylation reaction of 2-alkynoic acid derivatives
Lu,Zhu,Ma
, p. 7205 - 7206 (1992)
2-Alkynoic acid derivatives were hydroacetoxylated regio- and stereo-specifically by reaction with lithium acetate in HOAc at rt under the catalysis of palladium acetate to afford 3-acetoxy-2(Z)-alkenoic acid derivatives.
