78613-00-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78613-00-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,6,1 and 3 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 78613-00:
(7*7)+(6*8)+(5*6)+(4*1)+(3*3)+(2*0)+(1*0)=140
140 % 10 = 0
So 78613-00-0 is a valid CAS Registry Number.

Three trace impurities found in 4-acetyl-2-(2'-hydroxyethyl)-5,6-bis(4-chlorophenyl)-2H-pyridazin-3-one (II), a novel antihypertensive agent, were isolated by a combination of low-pressure liquid chromatography and preparative TLC. These impurities were i
