Check Digit Verification of cas no

The CAS Registry Mumber 1440537-79-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,0,5,3 and 7 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1440537-79:
(9*1)+(8*4)+(7*4)+(6*0)+(5*5)+(4*3)+(3*7)+(2*7)+(1*9)=150
150 % 10 = 0
So 1440537-79-0 is a valid CAS Registry Number.

Synthesis of Terminal N-Vinylazoles from Aromatic Aldehydes, DMSO, and Azoles Based DMSO as Terminal Carbon Synthon

, p. 4621 - 4626 (2021/09/02)

A protocol for the synthesis of terminal N-vinylazoles from aromatic aldehydes, DMSO, and azoles has been reported. In this strategy, DMSO was involved in the construction of the C=C bond as a terminal carbon synthon. Both aromatic aldehydes and azoles could be well tolerated and give the corresponding terminal N-vinylazoles in 52–91% yields. Based on preliminary experiments, a plausible mechanism is proposed. (Figure presented.).
