129242-48-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129242-48-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,2,4 and 2 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 129242-48:
(8*1)+(7*2)+(6*9)+(5*2)+(4*4)+(3*2)+(2*4)+(1*8)=124
124 % 10 = 4
So 129242-48-4 is a valid CAS Registry Number.

Intramolecular Diels-Alder reactions of pyrazines with alkynylphenyl moieties as side-chain dienophiles
Haider, Norbert,Van Der Plas, Henk C.
, p. 3641 - 3650 (2007/10/02)
Intramolecular Diels-Alder reactions of (2-alkynylphenyl-X)-pyrazines (X = O, NAc, S) under neutral and acidic conditions are described. The isomer distribution of the resulting tricyclic b- and c-annelated pyridines is discussed.
