Check Digit Verification of cas no

The CAS Registry Mumber 74074-50-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,0,7 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74074-50:
(7*7)+(6*4)+(5*0)+(4*7)+(3*4)+(2*5)+(1*0)=123
123 % 10 = 3
So 74074-50-3 is a valid CAS Registry Number.

Reactions with N-Acylimino-dithiocarbonic-acid-diesters

Augustin, M.,Richter, M.,Salas, S.

, p. 55 - 68 (2007/10/02)

Reactions of N-acylimino-dithiocarbonic-acid-S,S-diesters 1 with nucleophilic compounds present new possibilities to synthesize heterocycles.With amines 1a reacts by mono- and disubstitution, respectively, of methylthio-groups to isothioureas 2 and guanidines 3, with 1,2-binucleophilic arenes to benzoheterocycles 4, with aliphatic diamines to imidazolines 5, pyrimidines 6, diazepines 7 and the hexamethylene-diamine-derivatives 8. 1a reacts also with hydrazines to 1,2,4-triazoles 9 and with hydrazides to the thiosemicarbazones 10 or 1,3,4-oxadiazoles 11.Heterocyclisations of 1 with guanidines, thiourea, salts of thiourea and amidines give the 1,3,5-triazines 12, 14, 15 and 16.N-benzoyl-dithiocarbonic-acid-methylester -amid reacts with CH-acidic compounds to thiazoles 17.The structures of the final products are determined by i.r.-, 1H-n.m.r.-, u.v.- and mass-spectras.
