86209-36-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 86209-36-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,2,0 and 9 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 86209-36:
(7*8)+(6*6)+(5*2)+(4*0)+(3*9)+(2*3)+(1*6)=141
141 % 10 = 1
So 86209-36-1 is a valid CAS Registry Number.

2-propanedioic acids(2a-c) were denitrocyclized to coumarins (3a-c) by heating in quinoline in the presence of copper powder. 2-(4-Methoxiphenyl)-3-(2-nitrophenyl)-(Z)-2-propenoic acids (6a,b,d,e) were also similarly denitrocycli
