104824-51-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104824-51-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,8,2 and 4 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 104824-51:
(8*1)+(7*0)+(6*4)+(5*8)+(4*2)+(3*4)+(2*5)+(1*1)=103
103 % 10 = 3
So 104824-51-3 is a valid CAS Registry Number.

Synthesis of Furopyrimidine Derivatives via Reaction of 4-Methylpyrimidine-5-carboxylic Acids with Thionyl Chloride
Machon, Z.,Cieplik, J.
, p. 142 - 144 (2007/10/02)
6-Anilino-5-carboxy-4-methyl-2-phenylpyrimidines undergo an unusual reaction with thionyl chloride to give 4-anilino-5-oxo-2-phenyl-7-thioxo-5,7-dihydrofuropyrimidines, presumably via a sulfine as intermediate.
