Check Digit Verification of cas no

The CAS Registry Mumber 477515-22-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,7,5,1 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 477515-22:
(8*4)+(7*7)+(6*7)+(5*5)+(4*1)+(3*5)+(2*2)+(1*2)=173
173 % 10 = 3
So 477515-22-3 is a valid CAS Registry Number.

Synthesis of new 5-aryl tetrazoline from N-aceto hydrazide cyclic imides and study of biological activity

Al-Haidari, Akram S.,Al-Tamimi, Entesar O.

, p. 5647 - 5653 (2021/09/11)

The research resulted in the production of new tetrazoline derivatives. Firstly; the reaction of N-acetyl chloro cyclic imides with hydrazine hydrate to give compounds (1,2). Then, compounds (1,2) were reacted with different aromatic aldehydes to give Schiff bases (3-10). The compounds of N-( 2-chloro acetyl) cyclic imides were reacted with sodium azide to give N- (azido acetyl) cyclic imides (11,12). Finally, the reaction of the prepared Schiff bases compounds with azide compounds and cyclization to give 5-aryl tetrazoline on cyclic imides (13-20). The prepared compounds were characterized by FT-IR and some of them by 1H NMR, melting point, and were studied the effects of the preparing compounds on some strains of bacteria and fungi.
