Check Digit Verification of cas no

The CAS Registry Mumber 105516-47-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,5,1 and 6 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 105516-47:
(8*1)+(7*0)+(6*5)+(5*5)+(4*1)+(3*6)+(2*4)+(1*7)=100
100 % 10 = 0
So 105516-47-0 is a valid CAS Registry Number.

New Syntheses of Heterocycles with Vinyl- and Divinylcarbodiimides: Pyrroles, Triazoles, Pyrimidines, Pyrindines, Isoquinolines and Thiazolyl-isothiazoles

Capuano, Lilly,Hammerer, Volker,Huch, Volker

, p. 23 - 28 (2007/10/02)

The title compounds 3 and 4 react with diazomethane either by loss or by retention of the diazo nitrogen, to afford 3,4-dihydro-2-imino-2H-pyrroles 6 and 10 or the vic-triazole 5, respectively.The structure of 5 has been established by X-ray diffraction analysis. - The addition of benzylidene methylamine or alicyclic enamines 9 to 4 results in the formation of partially hydrogenated pyrimidine 7, pyrindine 11a or isoquinoline 11b. - Thermolysis of 4 proceeds with spontaneous dehydrogenation, giving high yields of 1-(1-indolyl)isoquinolines 8. - The derivative 10a, when melted with sulfur, undergoes both dehydrogenation and sulfur insertion, whereby the hitherto unknown thiazolyl-isothiazole 13 is formed.Its structure has been elucidated by an X-ray diffraction analysis. - A synthesis of the imidazoisoquinoline derivative 16 is reported. - Key Words: Carbodiimides, vinyl-, divinyl- / Imidazoisoquinoline
