Check Digit Verification of cas no
The CAS Registry Mumber 7493-59-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,9 and 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7493-59:
(6*7)+(5*4)+(4*9)+(3*3)+(2*5)+(1*9)=126
126 % 10 = 6
So 7493-59-6 is a valid CAS Registry Number.

In this communication we propose a convenient methodology to effect the oxidation of alkynes using ammonium persulfate and diphenyl diselenide as catalyst. The reactions effected in aqueous media lead to 1,2-unprotected dicarbonyl derivatives or to hemiacetals starting from terminal alkynes.
