67461-76-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 67461-76-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,4,6 and 1 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 67461-76:
(7*6)+(6*7)+(5*4)+(4*6)+(3*1)+(2*7)+(1*6)=151
151 % 10 = 1
So 67461-76-1 is a valid CAS Registry Number.

One-step conversion of 2-Amino- N ′-arylbenzamidines into 3-aryl-4-imino-3,4-dihydroquinazoline-2-carbonitriles using 4,5-dichloro-1,2,3- dithiazolium chloride

Mirallai, Styliana I.,Manos, Manolis J.,Koutentis, Panayiotis A.

, p. 9906 - 9913 (2013/10/22)

2-Amino-N′-arylbenzamidines react with 4,5-dichloro-1,2,3- dithiazolium chloride (Appel salt) in the presence of Huenig's base (2 equiv) to give in one step 3-aryl-4-imino-3,4-dihydroquinazoline-2-carbonitriles in 53-81% yields. Nine examples are presented along with the single-crystal X-ray structure of 4-imino-3-phenyl-3,4-dihydroquinazoline-2-carbonitrile. Furthermore, the behavior of the latter toward both acid and base hydrolysis is investigated. All new compounds are fully characterized, and a mechanistic rationale for the formation of the iminoquinazolines is provided.
