126751-40-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 126751-40-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,7,5 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 126751-40:
(8*1)+(7*2)+(6*6)+(5*7)+(4*5)+(3*1)+(2*4)+(1*0)=124
124 % 10 = 4
So 126751-40-4 is a valid CAS Registry Number.

AROMATIZATION OF ALIPHATIC COMPOUNDS. X. DIHYDROCINNOLINONES AND 1-AMINOOXINDOLES
Bonanomi, Michele,Baiocchi, Leandro
, p. 445 - 448 (2007/10/02)
When treated with thionyl chloride, some 7-substituted 4,4a,5,6-tetrahydro-3(2H)-cinnolinones are dehydrogenated to 7-substituted 5,6-dihydro-3(2H)-cinnolinones, which may be then transformed into 1-aminooxindoles by action of methanolic KOH.
