541508-28-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 541508-28-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,1,5,0 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 541508-28:
(8*5)+(7*4)+(6*1)+(5*5)+(4*0)+(3*8)+(2*2)+(1*8)=135
135 % 10 = 5
So 541508-28-5 is a valid CAS Registry Number.

, p. 1355 - 1359 (2007/10/03)
A range of some novel pyrazole derivatives has been prepared in moderate to good yield by the reaction of 3-aryl-1-phenyl-1H-pyrazole-4-carbaldehydes 1a,b as a starting material with some reagents such as acylglycine, benzamidine hydrochloride, malononitr
