Check Digit Verification of cas no
The CAS Registry Mumber 117103-44-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,1,0 and 3 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 117103-44:
(8*1)+(7*1)+(6*7)+(5*1)+(4*0)+(3*3)+(2*4)+(1*4)=83
83 % 10 = 3
So 117103-44-3 is a valid CAS Registry Number.

NOVEL RING TRANSFORMATIONS OF PYRAZINES BY INTRAMOLECULAR DIELS-ALDER REACTIONS
De Bie, D.A.,Ostrowicz, A.,Geurtsen, G.,Van Der Plas, H.C.
, p. 2977 - 2984 (2007/10/02)
Pyrazines carrying the ω-alkyne side-chain -XCH2CH2CH, (X = O,N,S,SO,SO2,C(CN)2) undergo on heating an intramolecular Diels-Alder reaction.Pyrazines with the electron donating atom (O,N or S) in the side-chain afford -fused pyridines as main products, whereas (3-butynylsulfinyl)pyrazine and (3-butynylsulfonyl)pyrazine are exclusively converted into -fused pyridines.A -fused pyridine is also the major product in the reaction of 2,5-bis(1,1-dicyano-4-pentynyl)pyrazine.
