228406-32-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 228406-32-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,8,4,0 and 6 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 228406-32:
(8*2)+(7*2)+(6*8)+(5*4)+(4*0)+(3*6)+(2*3)+(1*2)=124
124 % 10 = 4
So 228406-32-4 is a valid CAS Registry Number.

A dimroth rearrangement of pyrimidine nucleosides
Loakes, David,Brown, Daniel M.,Salisbury, Stephen A.
, p. 1333 - 1337 (2007/10/03)
N4-Acylamino-2′-deoxycytidine derivatives, 4a-c, undergo acid-promoted cyclisation to give [1,2,4]triazolo-[4,3-c]pyrimidin-5(6H)-ones, 5a-c, in the presence of pyridinium chloride. This reaction has been demonstrated for a series of analogues.
