74477-19-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74477-19-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,7 and 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 74477-19:
(7*7)+(6*4)+(5*4)+(4*7)+(3*7)+(2*1)+(1*9)=153
153 % 10 = 3
So 74477-19-3 is a valid CAS Registry Number.

RING-CHAIN ISOMERISM OF 3-HYDROXY-3-(2-IMIDAZOLYL)ISOINDOLINONES
Karlivan, G.A.,Valter, R.E.
, p. 247 - 251 (2007/10/02)
It was established by IR, UV, and PMR spectroscopy that N-unsubstituted and N-(n-alkyl, sec-alkyl, or aryl)-2-(2-imidazolylcarbonyl)benzamides obtained from imidazoisoquinoline-5,10-dione and ammonia or amines have the 3-(2-imidazolyl)isoindolinone
