24118-24-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 24118-24-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,1,1 and 8 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 24118-24:
(7*2)+(6*4)+(5*1)+(4*1)+(3*8)+(2*2)+(1*4)=79
79 % 10 = 9
So 24118-24-9 is a valid CAS Registry Number.

1,4-Benzoquinones: Improved Methods of Synthesis and New Diaziridinyl Analogues
Dzielendziak, Adam,Butler, John
, p. 643 - 645 (2007/10/02)
Two methods are given for the synthesis of 2,5-dichloro-3,6-bis(alkoxycarbonylamino)-1,4-benzoquinones 4, which can be subsequently reacted with aziridine to produce novel 2,5-di(1-aziridinyl)-3,6-bis(alkoxycarbonylamino)-1,4-benzoquinones 5.The first met
