Check Digit Verification of cas no
The CAS Registry Mumber 118043-63-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,0,4 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 118043-63:
(8*1)+(7*1)+(6*8)+(5*0)+(4*4)+(3*3)+(2*6)+(1*3)=103
103 % 10 = 3
So 118043-63-3 is a valid CAS Registry Number.

The homolytic acylation of various monosubstituted pyrazines was studied for a wide spectrum of substituents.Methoxy and chloro substituents were found to direct ortho substitution, thus giving the corresponding 2,3-disubstituted pyrazines.Acetyl, carbethoxy, and carboxamide groups were found to direct para substitution, thus leading to the corresponding 2,5-disubstituted pyrazines.These selectivities result from the combination of the inductive and resonance effects of the substituents.The synthetic potential of the acylation reaction is demonstrated in the preparation of some novel pyrazine flavorants.
