939671-14-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 939671-14-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,9,6,7 and 1 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 939671-14:
(8*9)+(7*3)+(6*9)+(5*6)+(4*7)+(3*1)+(2*1)+(1*4)=214
214 % 10 = 4
So 939671-14-4 is a valid CAS Registry Number.

Determination of the R → S enantiomerization barrier in 5,6-dihydrobenzoimidazo[1,2-c]quinazolines
Morozov,Kurbatov
, p. 758 - 765 (2012/11/07)
Chiral imidazoquinazolines undergoing thermally induced reversible R → S enantiomerization have been synthesized by the interaction of 2-(o-aminophenyl)benzimidazoles with aldehydes and ketones. The benzimidazole fragment has been used for the first time
