Check Digit Verification of cas no

The CAS Registry Mumber 642453-10-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,2,4,5 and 3 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 642453-10:
(8*6)+(7*4)+(6*2)+(5*4)+(4*5)+(3*3)+(2*1)+(1*0)=139
139 % 10 = 9
So 642453-10-9 is a valid CAS Registry Number.

Novel Synthesis of 2-Oxo-3-butynoates by Copper-Catalyzed Cross-Coupling Reaction of Terminal Alkynes and Monooxalyl Chloride

Guo, Minjie,Li, Dao,Zhang, Zhaoguo

, p. 10172 - 10174 (2007/10/03)

A general and efficient Cu(I)-catalyzed cross-coupling reaction of terminal alkynes and monooxalyl chloride for the synthesis of 2-oxo-3-butynoates and 2-oxo-3-butynoamides was developed. Readily available starting materials, the mild reaction conditions, wide functional group tolerance, and the obviation of stoichiometric organolithium or magnesium reagents combine to highlight this reaction.
