34140-01-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 34140-01-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,1,4 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 34140-01:
(7*3)+(6*4)+(5*1)+(4*4)+(3*0)+(2*0)+(1*1)=67
67 % 10 = 7
So 34140-01-7 is a valid CAS Registry Number.

A NEW PATHWAY TO 1,3,4(2H)-ISOQUINOLINETRIONES AND SUBSTITUTED ISOINDOLINONES
Vekemans, Jozef,Hoornaert, Georges
, p. 943 - 950 (2007/10/02)
A new synthesis in the isoquinoline series is discussed: the reaction of appropriate benzamides and oxalyl chloride affords isoquinolinetrions along N-aroyloxamoyl chlorides.The solvent effect, the acid catalysis and the isomer distribution are accounted
