373357-16-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 373357-16-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,7,3,3,5 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 373357-16:
(8*3)+(7*7)+(6*3)+(5*3)+(4*5)+(3*7)+(2*1)+(1*6)=155
155 % 10 = 5
So 373357-16-5 is a valid CAS Registry Number.

Flav-4-ones on reaction with DMF/POCl3 gave 4-chloro-2-aryl-2H-chromene-3-carbaldehydes which on reaction with ethyl-3-aminocrotonate give under Hantszch reaction conditions ethyl-2-methyl-5-aryl-5H-chromeno[3,4-c]pyridine-1-carboxylates in good yields.
