57200-30-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 57200-30-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,2,0 and 0 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 57200-30:
(7*5)+(6*7)+(5*2)+(4*0)+(3*0)+(2*3)+(1*0)=93
93 % 10 = 3
So 57200-30-3 is a valid CAS Registry Number.

SELECTIVE O- AND N3-ALKYLATION OF 2-ALKYLTHIO-4-HYDROXYPYRIMIDINES
Vainilavichyus, P. I.,Syadyaryavichyute, V. Yu.
, p. 1332 - 1335 (2007/10/02)
The effect of a number of factors on the regioselectivity of alkylation of 2-alkylthio-4-hydroxypyrimidines by methyl bromoacetate has been studied.In non-polar and low-polarity solvents N3-alkylation predominated whereas O-alkylation occured i
