Check Digit Verification of cas no
The CAS Registry Mumber 4702-25-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,0 and 2 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4702-25:
(6*4)+(5*7)+(4*0)+(3*2)+(2*2)+(1*5)=74
74 % 10 = 4
So 4702-25-4 is a valid CAS Registry Number.

ELECTRON DEFICIENT HETEROAROMATIC AMMONIOAMIDATES, XVIII. THE SYNTHESIS AND PHOTOCHEMISTRY OF SOME N-ISOQUINOLINO(THIOAMIDATES)

Thioacylation of isoquinolinioamide furnished the N-isoquinolinio(thioamidates) 2a-2c.Depending on the solvent, 2c exists either as a mixture with its tricyclic tautomer 5, or exclusively as the latter.The NMR and mass spectra, and the photochemistry of compounds 2a-2c are discussed.The photoproducts obtained include 3,4-dimethoxybenzonitrile, 3,4-dimethoxy(thiobenzamide), O-ethyl thiocarbamate, 1(2H)-isoquinolinethione (7a), 1(2H)-isoquinolinone (7b) and thiadiazoloisoquinolin-4-ium-2-olate (8a).Differences between the fragmentation upon electron impact and the photochemistry of the thioamidates of Types 1 and 2, as well as between the photochemistry of the thioamidates 2 and their amidate counterparts of Type 3 are discussed.Potassium permanganate oxidation of thiadiazoloisoquinolin-4-ium-2-thiolate (8b) furnishes the olate 8a and 1-isoquinolyl thiocyanate (12).
