138768-58-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138768-58-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,7,6 and 8 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 138768-58:
(8*1)+(7*3)+(6*8)+(5*7)+(4*6)+(3*8)+(2*5)+(1*8)=178
178 % 10 = 8
So 138768-58-8 is a valid CAS Registry Number.

SYNTHESIS AND TAUTOMERISM OF 2,4-DIHYDROXYQUINOLINES
Ruano, Jose Luis Garcia,Pedregal, Concepcion,Rodriguez, Jesus H.
, p. 2151 - 2159 (2007/10/02)
The reaction of ethyl N-carbamates with NaH/THF yields 3-Z-2,4-dihydroxyquinolines .The study of the tautomeric equilibria of all these substrates by 13C-nmr shows that thioether and nitrile exhibit the 2-q
