74799-01-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74799-01-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,7,9 and 9 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 74799-01:
(7*7)+(6*4)+(5*7)+(4*9)+(3*9)+(2*0)+(1*1)=172
172 % 10 = 2
So 74799-01-2 is a valid CAS Registry Number.

Gupta, M.C.L.N.,Rao, V. Sudhakar,Darbarwar, Malleshwar
, p. 2103 - 2111 (2007/10/02)
A regiospecific route for 2,5-dioxo-5,6-dihydropyranoquinolines 4a-p has been developed by base catalysed reaction of 4-hydroxy-3-formyl quinolin-2(1H)-one 2a-c with active methylene compounds 3a-f in good yield.
