135039-38-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 135039-38-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,0,3 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 135039-38:
(8*1)+(7*3)+(6*5)+(5*0)+(4*3)+(3*9)+(2*3)+(1*8)=112
112 % 10 = 2
So 135039-38-2 is a valid CAS Registry Number.

It has been shown that chalcones react with 5,6-diamino-4-hydroxypyrimidine to form 2,3-dihydro-1H-pyrimido-1,5-diazepines but aromatic aldehydes and methyl ketones give the monoazomethines.The mechanism and tendency to form the 7-membered ring are
