1001421-88-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1001421-88-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,1,4,2 and 1 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1001421-88:
(9*1)+(8*0)+(7*0)+(6*1)+(5*4)+(4*2)+(3*1)+(2*8)+(1*8)=70
70 % 10 = 0
So 1001421-88-0 is a valid CAS Registry Number.

Complex α-pyrones synthesized by a gold-catalyzed coupling reaction
Luo, Tuoping,Schreiber, Stuart L.
, p. 8250 - 8253 (2008/09/18)
(Chemical Equation Presented) Sequential alkyne activation of readily available propargyl propiolates by a gold(I) catalyst yields compounds with α-pyrone skeletons (see scheme). An intermediate oxocarbenium ion converts into distinct products by two path
