Check Digit Verification of cas no
The CAS Registry Mumber 1031407-18-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,1,4,0 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1031407-18:
(9*1)+(8*0)+(7*3)+(6*1)+(5*4)+(4*0)+(3*7)+(2*1)+(1*8)=87
87 % 10 = 7
So 1031407-18-7 is a valid CAS Registry Number.

Synthesis of highly substituted 2H-azirine-2-carboxylates via 3-azido-4-oxobut-2-enoates
Patonay, Tamas,Jeko, Jozsef,Juhasz-Toth, Eva
, p. 1441 - 1448 (2008)
Phenacyl azides have been transformed into ethyl 4-aryl-3-azido-2-methyl-4- oxobut-2-enoates by base-induced coupling of the starting α-azido ketone with ethyl pyruvate followed by elimination of methanesulfonic acid from the mesylate generated in situ fr
