Check Digit Verification of cas no
The CAS Registry Mumber 40155-28-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,1,5 and 5 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 40155-28:
(7*4)+(6*0)+(5*1)+(4*5)+(3*5)+(2*2)+(1*8)=80
80 % 10 = 0
So 40155-28-0 is a valid CAS Registry Number.

Studies on Pyrazines. 29. High Regioselective Synthesis of Chloropyrazines from 3-Substituted Pyrazine 1-Oxides
Sato, Nobuhiro,Fujii, Megumi
, p. 1177 - 1180 (2007/10/02)
Reaction of 3-methoxy- or 3-chloropyrazine 1-oxides with refluxing phosphoryl chloride in the presence of amine led to a high regioselective formation of 3-substituted 2-chloropyrazines.In contrast, the use of chloroacetyl chloride instead of phosphoryl chloride enabled different regioselectivity to yield 6-substituted 2-chloropyrazines, particularly 3-methoxycarbonylpyrazine 1-oxide was almost exclusively converted into methyl 6-chloropyrazinecarboxylate under conditions without the amine.
