136809-67-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 136809-67-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,8,0 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 136809-67:
(8*1)+(7*3)+(6*6)+(5*8)+(4*0)+(3*9)+(2*6)+(1*7)=151
151 % 10 = 1
So 136809-67-1 is a valid CAS Registry Number.

, p. 469 - 474 (2007/10/03)
A series of some new aryl imidazole quinoline-2-ones have been synthesized by condensing N-[-(Z)-1-(Hydrazino carbonyl)-2-Phenyl vinyl]acetamide with simple and substituted coumarins in acetic acid by two step process (method-A) and one pot process (metho
